[jira] [Updated] (MCOMPILER-511) proc:only doesn't work as expected
[ https://issues.apache.org/jira/browse/MCOMPILER-511?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Stefan Röck updated MCOMPILER-511:
----------------------------------
Description:
According to the docs [https://maven.apache.org/plugins/maven-compiler-plugin/compile-mojo.html#proc,] *proc:only* should only process annotation processors but *not* trigger compilation. However, files are always compiled with the following config:
{code}
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>3.10.1</version>
<executions>
<execution>
<id>process</id>
<phase>generate-sources</phase>
<goals>
<goal>compile</goal>
</goals>
<configuration>
<annotationProcessors>
<processor>org.immutables.processor.ProxyProcessor</processor>
</annotationProcessors>
<proc>only</proc>
</configuration>
</execution>
</executions>
</plugin>
{code}
See small reproducer repo at https://github.com/stefanroeck/annotationtest
In the logs I can see that the prop is passed through, but still 2 classes are compiled:
{code}
21:12:25,407 [DEBUG] -d C:\dev\IdeaProjects\annotationtest\target\classes -classpath C:\dev\IdeaProjects\annotationtest\target\classes;C:\Dev\.m2\repository\org\immutables\value\2.8.8\value-2.8.8.jar; -sourcepath C:\dev\IdeaProjects\annotationtest\src\main\java;C:\dev\IdeaProjects\annotationtest\target\generated-sources\annotations; -s C:\dev\IdeaProjects\annotationtest\target\generated-sources\annotations -proc:only -processor org.immutables.processor.ProxyProcessor -g -nowarn -target 17 -source 17 -encoding UTF-8
