Fix alpine failures by switching default back to only warn on verification failures. To prevent build failures due to missing GPG or rotated vendor keys. (#1262)

Also allow multiple GPG keys to be provided.

 - Migrated the action implementation to ESM to support the latest `@actions/*` packages.
-- Added the `oracle-openjdk` distribution for OpenJDK builds from Oracle.
+- Added Oracle OpenJDK (`oracle-openjdk`), Red Hat Build of OpenJDK (`redhat`), and Liberica Native Image Kit (`liberica-nik`), and expanded Tencent Kona support through JDK 25.
 - Added `java-version: latest` to resolve the newest stable GA release from the distribution's remote metadata.
-- JDK downloads now automatically verify authoritative checksums for [supported distributions](#download-integrity-and-signatures).
+- Expanded install compatibility with JEP 322 multi-field versions such as `18.0.1.1`, Temurin `jdk+jmods` packages, and native musl artifacts on Alpine for Dragonwell, Corretto, Zulu, and Liberica.
+- JDK downloads now automatically verify authoritative checksums. Package signature verification is supported for Temurin and Microsoft builds, with configurable strict enforcement.
 - Added `force-download: true` to bypass the tool cache and perform a reproducible fresh install.
 - Dependency caching now supports custom paths with `cache-path` and restore-only operation with `cache-read-only: true`.
+- Dependency cache keys now include `.mvn/extensions.xml` and `gradle.properties`, preventing stale restores when Maven extensions or Gradle dependency properties change.
 - Downloaded JDKs are now [cached](#caching-jdk-installations) automatically when `cache` is set; use `cache-jdk` to enable or disable it independently.
+- Warm JDK-cached jobs can reuse cached release metadata, avoiding vendor API calls while retaining a stale-metadata fallback for vendor outages and rate limits.
+- Maven configuration now supports multiple server credentials and custom dependency-resolution repositories.
+- Maven signing keys are imported into an isolated temporary GPG home instead of the runner's default keyring.
 - Set `problem-matcher: false` to disable Java compiler and uncaught-exception annotations.
 - GraalVM distributions now set `GRAALVM_HOME` in addition to `JAVA_HOME`.
 - Invalid boolean values, unsupported distribution/package/platform combinations, and mismatched Maven toolchain ID counts now fail with targeted errors.

 - Legacy AdoptOpenJDK distributions were removed. Use `temurin` instead of `adopt` or `adopt-hotspot`, and `semeru` instead of `adopt-openj9`.

 Distributions or individual releases without an authoritative checksum continue to install normally, with the omission reported in debug logs. Installations resolved directly from the runner tool cache — including JDKs preinstalled on the runner image and JDKs installed by an earlier step of the same job — are not downloaded again and are not reverified, even when `verify-signature: true` is set. Use `force-download: true` to always download and verify the archive.
 
-Use `verify-signature: true` to verify package signatures for distributions that support it. Currently supported distributions are `temurin` and `microsoft`; setting it for an unsupported distribution fails the workflow.
+Package signature verification is supported for `temurin` and `microsoft`. When `verify-signature` is omitted, the action checks the signature and warns if GPG is unavailable or verification fails, but does not enforce the result. Explicitly setting `verify-signature: true` enforces verification and makes these failures fatal. Setting `verify-signature: true` for an unsupported distribution also fails the workflow.
+
+> [!WARNING]
+> Requesting explicit signature verification with verify-signature can fail a build after an unexpected but legitimate vendor signing-key rotation, because the action's bundled keys may not yet include the new key. Confirm a new key through the vendor's trusted documentation before using it.
+
+After confirming a legitimate rotation, configure the updated key with `verify-signature-public-key`. The input accepts one or more ASCII-armored public keys; concatenate complete armored key blocks when both old and new vendor keys are needed during a transition. Custom keys replace, rather than extend, the keys bundled with the selected distribution.

+As a temporary fallback while a legitimate rotation is being investigated, set `verify-signature: false`. This disables package signature verification, although authoritative checksum verification still applies when the vendor publishes a checksum.

 ## Selecting a Java distribution
 `java-version` and `distribution` select what gets installed. `java-version` may be replaced by `java-version-file`, and `distribution` is optional only when `java-version-file` points to a `.sdkmanrc` or `.tool-versions` file that carries a recognized vendor identifier. In every other case both inputs must be provided. See [Supported distributions](../README.md#Supported-distributions) for a list of available options.

+### Resolving Maven dependencies from custom repositories
+
+Use `mvn-repositories` when Maven must download dependencies from repositories
+outside Maven Central. Each line has the format
+`repository-id:repository-url:snapshots-enabled`. The parser uses the first and
+last colons as separators, so repository URLs can contain a scheme or port.
+
+The repository ID can match a `mvn-server-credentials` server ID to authenticate
+requests to a private repository:
+
+```yaml
+steps:
+  - uses: actions/checkout@v7
+  - name: Set up Java and private Maven repositories
+    uses: actions/setup-java@v6

+      PRIVATE_REPOSITORY_TOKEN: ${{ secrets.PRIVATE_REPOSITORY_TOKEN }}
+```
+
+This configuration adds the following active profile to `settings.xml`:
+
+```xml
+<profiles>
+  <profile>
+    <id>setup-java-repositories</id>
+    <repositories>
+      <repository>
+        <id>central</id>
+        <url>https://repo.maven.apache.org/maven2</url>
+        <snapshots>
+          <enabled>false</enabled>
+        </snapshots>
+      </repository>
+      <repository>
+        <id>private</id>
+        <url>https://maven.example.com:8443/releases</url>
+        <snapshots>
+          <enabled>false</enabled>
+        </snapshots>

+  </profile>
+</profiles>
+<activeProfiles>
+  <activeProfile>setup-java-repositories</activeProfile>
+</activeProfiles>
+```
+
+Maven Central is included first by default. Set
+`mvn-repositories-prioritize-central: false` to place custom repositories
+first, or set `mvn-repositories-include-central: false` to disable Central. The
+generated profile overrides the Central repository inherited from Maven's Super
+POM with releases and snapshots disabled. When automatic Central inclusion is
+off, the ID `central` may instead be declared explicitly in `mvn-repositories`
+to replace it with a user-specified repository; otherwise that ID is reserved
+to prevent duplicate entries.

 ### GPG
 
 The example above uses the [Maven GPG Plugin](https://maven.apache.org/plugins/maven-gpg-plugin/)'s Bouncy Castle signer (`-Dgpg.signer=bc`, available since `maven-gpg-plugin` 3.2.0). It is a pure-Java signer that reads the key directly from the `MAVEN_GPG_KEY` environment variable, so it does **not** require the `gpg` executable, importing the key into a GPG keychain, or the `--pinentry-mode loopback` workaround in your `pom.xml`. The key must be an ASCII-armored secret key (transferable secret key format).
