Vincent Massol commented on MCOMPILER-122:
------------------------------------------
I've hit this problem too.
I've had to do the following
(https://github.com/xwiki/xwiki-commons/blob/master/pom.xml#L762):
{noformat}
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<!-- Lock down plugin version for build reproducibility -->
<version>3.2</version>
<configuration>
<source>1.7</source>
<target>1.7</target>
</configuration>
<executions>
<!-- We need custom sourcepaths for our Component Annotation
Process work
(See ComponentCheckerAnnotationProcessor.java). This is
required because of
http://jira.codehaus.org/browse/MCOMPILER-122.
However note that IntelliJ IDEA doesn't honor custom
sourcepaths, see
https://youtrack.jetbrains.com/issue/IDEA-133120, which means
that you need to turn off
Annotation Processing in IDEA or IDEA will generate errors
while building modules -->
<execution>
<id>default-compile</id>
<configuration>
<compilerArguments>
<sourcepath>${project.basedir}/src/main/java:${project.basedir}/src/main/resources</sourcepath>
</compilerArguments>
</configuration>
</execution>
<execution>
<id>default-testCompile</id>
<configuration>
<compilerArguments>
<sourcepath>${project.basedir}/src/test/java:${project.basedir}/src/test/resources</sourcepath>
</compilerArguments>
</configuration>
</execution>
</executions>
</plugin>

However this isn't perfect. It works in Maven but fails in IDEA (see
https://youtrack.jetbrains.com/issue/IDEA-133120). I'm also not sure it works
on Windows machines (but that could be fixed with profiles).
In addition I've noticed that it runs javac with 2 -sourcepath parameters! For
example:
{noformat}
[DEBUG] -d
/Users/vmassol/dev/xwiki/git/xwiki-commons/xwiki-commons-core/xwiki-commons-stability/target/classes
-classpath
/Users/vmassol/dev/xwiki/git/xwiki-commons/xwiki-commons-core/xwiki-commons-stability/target/classes:/Users/vmassol/.m2/repository/org/xwiki/commons/xwiki-commons-tool-component-generation/6.4-SNAPSHOT/xwiki-commons-tool-component-generation-6.4-SNAPSHOT.jar:
-sourcepath
/Users/vmassol/dev/xwiki/git/xwiki-commons/xwiki-commons-core/xwiki-commons-stability/src/main/java:/Users/vmassol/dev/xwiki/git/xwiki-commons/xwiki-commons-core/xwiki-commons-stability/target/generated-sources/annotations:
-s
/Users/vmassol/dev/xwiki/git/xwiki-commons/xwiki-commons-core/xwiki-commons-stability/target/generated-sources/annotations
-g -deprecation -target 1.7 -source 1.7 -encoding UTF-8 -sourcepath
/Users/vmassol/dev/xwiki/git/xwiki-commons/xwiki-commons-core/xwiki-commons-stability/src/main/java:/Users/vmassol/dev/xwiki/git/xwiki-commons/xwiki-commons-core/xwiki-commons-stability/src/main/resources
-Xlint:all
{noformat}
And luckily it seems javac will take the last one...
In any case it would be great to fix it :)
Thanks

> Project: Maven Compiler Plugin
> Issue Type: Bug
> Affects Versions: 2.1
> Reporter: Milos Kleint
>
> annotation processors which load non-Java resources from the sourcepath, will
> currently get only the src/main/java folder.
> Unfortunately just adding src/main/resources to -sourcepath does not suffice,
> due to a bug in javac:
