Gili created MJAVADOC-704:
-----------------------------
Summary: Javadoc plugin does not respect jdkToolchain
Key: MJAVADOC-704
URL: https://issues.apache.org/jira/browse/MJAVADOC-704
Project: Maven Javadoc Plugin
Issue Type: Bug
Components: jar
Affects Versions: 3.3.1
Reporter: Gili
If I run the following using JDK 8:
{code:java}
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-javadoc-plugin</artifactId>
<version>3.3.1</version>
<executions>
<execution>
<id>attach-javadocs</id>
<goals>
<goal>jar</goal>
</goals>
<configuration>
<jdkToolchain>
<version>11</version>
</jdkToolchain>
<!-- ... --->
</execution>
</executions>
</plugin>{code}
I get:
{code:java}
[INFO] Toolchain in maven-javadoc-plugin: JDK[C:\Program Files\Java\jdk-11.0.2]
org.apache.maven.lifecycle.LifecycleExecutionException: Failed to execute goal
org.apache.maven.plugins:maven-javadoc-plugin:3.3.1:jar (attach-javadocs) on
project core: Execution attach-javadocs of goal
org.apache.maven.plugins:maven-javadoc-plugin:3.3.1:jar failed.
[...]
Caused by: java.lang.UnsupportedOperationException
at
org.codehaus.plexus.languages.java.jpms.CmdModuleNameExtractor.getModuleName
(CmdModuleNameExtractor.java:46){code}
If I run the same code using JDK 11 I get past this point (I get an error
relating to the contents of module-info):
{code:java}
[ERROR] Failed to execute goal
org.apache.maven.plugins:maven-javadoc-plugin:3.3.1:jar (attach-javadocs) on
project core: MavenReportException: Error while generating Javadoc:

[ERROR]
[ERROR] Refer to the generated Javadoc files in
'C:\Users\Gili\Documents\pouch\core\target\apidocs' dir.
[ERROR]
[ERROR] -> [Help 1] {code}
This seems to imply that {{jdkToolchain}} is being ignored.
On the other hand, if I use {{jdkToolchain}} with the maven-compiler-plugin it
seems to work just fine. My toolchains.xml file contains:
{code:java}
<?xml version="1.0" encoding="UTF8"?>
<toolchains>
<toolchain>
<type>jdk</type>
<provides>
<version>11</version>
<vendor>oracle</vendor>
</provides>
<configuration>
<jdkHome>C:\Program Files\Java\jdk-11.0.2</jdkHome>
</configuration>
</toolchain>
</toolchains> {code}
Am I doing anything wrong? Or is this a possible bug in the plugin?
