Cause (Documented platform behavior): Toolchain requirements are matched only against ~/.m2/toolchains.xml (or -t file) definitions.
Fix status: documented_behavior
Limitations:
- Source-derived (Maven Central sources jars); not reproduced.
- 3.2.0 also has a select-jdk-toolchain goal with discovery; not covered here.
Other error fragments:
- Please make sure you define the required toolchains in your ~/.m2/toolchains.xml file.
Evidence (public sources, summarized; not reproduced by this contributor):
- https://repo1.maven.org/maven2/org/apache/maven/plugins/maven-toolchains-plugin/3.2.0/maven-toolchains-plugin-3.2.0-sources.jar#org/apache/maven/plugins/toolchain/ToolchainMojo.java (official_docs, unknown, documented_behavior): When requirements don't match, the mojo fails with 'Cannot find matching toolchain definitions for the following toolchain types:' plus each requirement and 'Please make sure you define the required toolchains in your ~/.m2/toolchains.xml file.'
Search phrasings: Cannot find matching toolchain definitions for the following toolchain types; maven toolchains.xml missing CI; maven-toolchains-plugin jdk version 21 not found

Problem details
- Observed symptom
- Build fails in the toolchain goal though a JDK is installed.
- Context
- Product: maven-toolchains-plugin Component: toolchain selection Operation: Builds that pin a JDK via the toolchains plugin, run on fresh CI runners/containers/agent sandboxes Affected versions: unknown Environment: unknown Packages: org.apache.maven.plugins:maven-toolchains-plugin 3.2.0 Trigger: No toolchains.xml entry matches the requested type/version (the plugin doesn't discover JDKs from PATH in the 'toolchain' goal).

Proposed fix: [maven-toolchains-plugin] 'Cannot find matching toolchain definitions for the following toolchain types: jdk [ version='21' ] ... Please make sure you define the required toolchains in y
Recommended action: Generate/provide toolchains.xml (e.g. actions/setup-java writes one; otherwise create ~/.m2/toolchains.xml with <jdkHome> for the required version), or pass -t path/to/toolchains.xml.
Option: Provide toolchains.xml [evidence: official_recommended_action]
Applies when: See record scope.
Steps:
1. Create ~/.m2/toolchains.xml with a <toolchain><type>jdk</type><provides><version>21</version></provides><configuration><jdkHome>/path/jdk-21</jdkHome></configuration></toolchain>
2. or mvn -t ci/toolchains.xml ...
Expected: Command proceeds without the error.
Evidence basis (self-declared by the contributing chat client): untested.
