Give latest+qualifier inputs (e.g. latest-ea) a targeted error

Inputs like 'latest-ea' had their '-ea' suffix stripped and fell through
to the generic SemVer validation, failing with a confusing "'latest' is
not valid SemVer" message even though 'latest' is supported. Add an
explicit guard so any 'latest*' value other than exactly 'latest' throws
a targeted error explaining that 'latest' resolves GA releases only and
cannot be combined with '-ea' or other qualifiers.

Note the Oracle JDK license caveat below still applies to a floating `latest`.

 The action has a built-in functionality for caching and restoring dependencies. It uses [toolkit/cache](https://github.com/actions/toolkit/tree/main/packages/cache) under hood for caching dependencies but requires less configuration settings. Supported package managers are gradle, maven and sbt. The format of the used cache key is `setup-java-${{ platform }}-${{ packageManager }}-${{ fileHash }}`, where the hash is based on the following files:
 
 - gradle: `**/*.gradle*`, `**/gradle-wrapper.properties`, `buildSrc/**/Versions.kt`, `buildSrc/**/Dependencies.kt`, `gradle/*.versions.toml`, and `**/versions.properties`
-- maven: `**/pom.xml` and `**/.mvn/wrapper/maven-wrapper.properties`
+- maven: `**/pom.xml`, `**/.mvn/wrapper/maven-wrapper.properties`, and `**/.mvn/extensions.xml`
 - sbt: all sbt build definition files `**/*.sbt`, `**/project/build.properties`, `**/project/**.scala`, `**/project/**.sbt`
 
 When the option `cache-dependency-path` is specified, the hash is based on the matching file. This option supports wildcards and a list of file names, and is especially useful for monorepos.
 
 The workflow output `cache-hit` is set to indicate if an exact match was found for the key [as actions/cache does](https://github.com/actions/cache/tree/main#outputs).
 
+The workflow output `cache-primary-key` exposes the primary cache key computed by the action for the configured build tool. It is useful for composing with [`actions/cache`](https://github.com/actions/cache) or [`actions/cache/restore`](https://github.com/actions/cache/tree/main/restore) in later steps or dependent jobs that need to reuse the exact same key. It is empty when caching is not enabled or when caching is skipped (for example, when the cache service is unavailable).
+
 The cache input is optional, and caching is turned off by default.
 
+**Maven Wrapper:** when `cache: 'maven'` is enabled, the action also caches and restores the Maven Wrapper distribution downloaded to `~/.m2/wrapper/dists` (in addition to the local repository), so wrapper-based (`./mvnw`) builds don't re-download the wrapper on every run. This is keyed on `**/.mvn/wrapper/maven-wrapper.properties` as shown above.

+## Ensuring the Maven cache is complete (plugin dependencies)
+
+When you enable `cache: maven`, the action caches your local Maven repository
+(`~/.m2/repository`) and downloaded Maven Wrapper distributions
+(`~/.m2/wrapper/dists`). The cache key is a hash of your Maven inputs — every
+`**/pom.xml`, plus `**/.mvn/wrapper/maven-wrapper.properties` and
+`**/.mvn/extensions.xml` — so changing any of those files (for example bumping
+the wrapper version or editing core extensions) produces a new key and
+invalidates the cache. At the end of the job the action saves whatever was
+downloaded during that run. It does **not** re-save the cache when the key
+already matches (a cache *hit*).
+
+Maven resolves **plugin** dependencies lazily: it only downloads the plugins and
+plugin dependencies required by the goals that actually execute. As a result, the
+run that first creates the cache determines what is stored. If that run executed a
+"thin" goal such as `mvn compile`, plugins bound to later phases are never
+resolved. For example, `maven-shade-plugin` (bound to `package`) pulls in
+`plexus-archiver`, `commons-compress`, `io.airlift:aircompressor` and
+`org.tukaani:xz` — none of which a `compile` run downloads. Those artifacts are
+therefore absent from the cache, and because the action does not re-save on a
+hit, every later `test`/`verify`/`package` job re-downloads them on every run.
+
+### Seed the cache with a resolution step
+
+To populate `~/.m2` as comprehensively as possible on the run that creates the
+cache, run a dependency-resolution "seed" command before your build. Choose a
+command based on how thorough you need it to be:
+
+| Seed command | Resolves plugin dependencies? | Notes |
+|--------------|:-----------------------------:|-------|
+| `mvn dependency:resolve` | No | Resolves project dependencies only — misses plugin dependencies (e.g. `aircompressor`). |
+| `mvn dependency:resolve-plugins` | Yes | Resolves plugins **and their dependencies**. |
+| `mvn dependency:go-offline` | Yes | Resolves project and plugin dependencies (a superset). |
+| `mvn dependency:go-offline dependency:resolve-plugins` | Yes (most thorough) | Recommended default. Use `dependency:resolve dependency:resolve-plugins` if `go-offline` is flaky or insufficient for your project. |
+
+Single job — seed, then build (the cache saved at the end of this run contains
+the full set):
+
+```yaml
+steps:
+- uses: actions/checkout@v6
+- uses: actions/setup-java@v5
+  with:
+    distribution: 'temurin'
+    java-version: '25'
+    cache: 'maven'
+- name: Seed the Maven cache
+  run: mvn -B dependency:go-offline dependency:resolve-plugins
+- name: Build with Maven
+  run: mvn -B verify --file pom.xml
+```
+
+Separate seed job — useful for a matrix where different legs run different goals
+(`test`, `check`, `verify`, `-Pprofile1`, ...) but all share the same `~/.m2`
+cache. Without a seed, whichever job finishes first creates the cache from its
+own partial `.m2`, and parallel jobs race to save an equally partial cache; the
+seed job instead creates one comprehensive cache that every other job reuses:
+
+```yaml
+jobs:
+  seed-cache:
+    runs-on: ubuntu-latest
+    steps:
+    - uses: actions/checkout@v6
+    - uses: actions/setup-java@v5
+      with:
+        distribution: 'temurin'
+        java-version: '25'
+        cache: 'maven'
+    - name: Seed the Maven cache
+      run: mvn -B dependency:go-offline dependency:resolve-plugins
+
+  build:
+    needs: seed-cache
+    runs-on: ubuntu-latest
+    strategy:
+      matrix:
+        goal: ['test', 'verify', 'test -Pprofile1']
+    steps:
+    - uses: actions/checkout@v6
+    - uses: actions/setup-java@v5
+      with:
+        distribution: 'temurin'
+        java-version: '25'
+        cache: 'maven'
+    - name: Build
+      run: mvn -B ${{ matrix.goal }} --file pom.xml
+```
+
+### Caveats
+
+- **The seed only helps on the run that creates the cache.** Once a cache exists
+  for the current `pom.xml` hash, later runs get a hit and any additional
+  downloads are not saved. On an existing repository whose cache is already
+  incomplete, invalidate it once (for example by changing `cache-dependency-path`
+  or deleting the repository's caches) so a complete cache is created from the
+  seed.
+- **Static resolution is not exhaustive.** `go-offline`/`resolve-plugins` resolve
+  the statically declared plugin set for the *active* profiles and modules.
+  Profile-gated plugins, conditionally-active modules, and artifacts a plugin
+  fetches at execution time may still be missed. For the most complete cache,
+  seed with the fullest goal set your CI actually uses (for example
+  `mvn -B verify` with every profile enabled).
+- **Multi-module projects:** run the seed at the reactor root so every module's
+  plugins are resolved.
+
+> [!NOTE]
+> The same "the cache stores only what the creating run downloaded, and is not
+> re-saved on a hit" behavior applies to `cache: gradle`, since Gradle also
+> resolves dependencies and plugin/buildscript classpaths lazily. Gradle has no
+> direct equivalent of `dependency:go-offline`, so for complete and fine-grained
+> dependency caching on Gradle projects we recommend
+> [`gradle/actions/setup-gradle`](https://github.com/gradle/actions/tree/main/setup-gradle),
+> which provides purpose-built caching (see the
+> [setup-gradle documentation](https://github.com/gradle/actions/blob/main/docs/setup-gradle.md)).

+## Installing JDK without setting as default
+
+When installing multiple JDKs, the last one installed becomes the default (`JAVA_HOME`, `PATH`). Use the `set-default` option to install a JDK without overriding the default. The installed JDK is still discoverable via the `JAVA_HOME_<major>_<arch>` environment variable (e.g. `JAVA_HOME_21_X64`).

+    echo "Java 21 path from output: ${{ steps.setup-java-21.outputs.path }}"
+```
+
+In this example, `JAVA_HOME` and `java` on `PATH` point to Java 17, while Java 21 is available via `JAVA_HOME_21_X64` or the step output `path`.
+
+> **Note:** When a single step installs multiple JDKs via a multiline `java-version`, the `set-default` value applies to all of them. With `set-default: false`, none of those JDKs become the default; each remains discoverable through its `JAVA_HOME_<major>_<arch>` variable. Regardless of `set-default`, installed JDKs are still registered in the Maven toolchains file, so they can be selected via Maven toolchains.
+
 ## Installing Java from local file
 If your use-case requires a custom distribution or a version that is not provided by setup-java, you can download it manually and setup-java will take care of the installation and caching on the VM:
 
 > [!NOTE]
-> This approach also lets you use builds that setup-java does not provide directly, such as **Early Access (EA)** or other unreleased JDK builds (for example, an upcoming feature release or a Loom/Valhalla preview build). Download the desired archive in a prior step and point `jdkFile` at it; setup-java will extract, install, and cache it just like a supported distribution. When targeting multiple architectures, select the correct binary per architecture in your workflow (for example, with a build matrix).

+## Java problem matcher (compiler annotations)
+
+`setup-java` registers a [problem matcher](https://github.com/actions/toolkit/blob/main/docs/problem-matchers.md) for Java after installing the JDK. It scans the log output of subsequent steps and turns `javac` diagnostics into GitHub [annotations](https://docs.github.com/actions/using-workflows/workflow-commands-for-github-actions#setting-a-warning-message) that appear in the run summary and inline on the affected files. It matches two kinds of lines:
+
+- Compiler errors and warnings, e.g. `App.java:12: error: cannot find symbol` (owner `javac`).
+- Uncaught-exception header lines, e.g. `Exception in thread "main" ...`; because these lines have no file or line captures, they appear as log/run-level annotations rather than inline file annotations (owner `java`).
+
+This is enabled by default and requires no configuration.
+
+### Disabling the problem matcher
+
+There is no action input to turn the matcher off, but you can disable it for the rest of the job with the built-in [`remove-matcher`](https://github.com/actions/toolkit/blob/main/docs/problem-matchers.md#remove-a-problem-matcher) workflow command. Pass the matcher **owner** (not a file name); the Java matcher defines two owners, `javac` and `java`, so remove both to fully suppress it:
+
+```yaml
+jobs:
+  build:
+    runs-on: ubuntu-latest
+
+    steps:
+    - uses: actions/checkout@v6
+    - uses: actions/setup-java@v5

+
+    - name: Build with Maven
+      run: mvn -B package --file pom.xml
+```
+
+***NOTES***:
+- `remove-matcher` only stops annotations from being created; the underlying compiler output is unchanged, so a failing `javac`/build still fails the step.
+- The command is scoped to the job, so add the step right after `setup-java` (and before your build) in every job where you want the matcher disabled.
