John Patrick created MCOMPILER-422:
--------------------------------------
Summary: multi release jar issue exporting release version only
packages
Key: MCOMPILER-422
URL: https://issues.apache.org/jira/browse/MCOMPILER-422
Project: Maven Compiler Plugin
Issue Type: Improvement
Affects Versions: 3.8.1
Reporter: John Patrick
I'm having to add ModuleInfoHack.java in empty packages so that compiler works,
then do excludes **/ModuleInfoHack.java at package time.
The simplest example is;
{code}
src/main/java/package/a/Example1.java (1)
src/main/java/package/b/Example2.java (2)
src/main/java11/package/b/Example2.java (3)
src/main/java11/module-info.java (4)
{code}
With module-info.java looking like;
{code}
module MODULE_A {
exports package.a;
exports package.b;
}
{code}
I get compile errors so I need to create this structure adding (5);
{code}
src/main/java/package/a/Example1.java (1)
src/main/java/package/b/Example2.java (2)
src/main/java11/package/a/ModuleInfoHack.java (5)
src/main/java11/package/b/Example2.java (3)
src/main/java11/module-info.java (4)
{code}
The maven compiler plugin has this configuration;
{code}
<executions>
<execution>
<id>java11-main</id>
<phase>compile</phase>
<goals>
<goal>compile</goal>
</goals>
<configuration>
<release>11</release>
<jdkToolchain>
<version>11</version>
</jdkToolchain>
<compileSourceRoots>
<compileSourceRoot>${project.basedir}/src/main/java11</compileSourceRoot>
</compileSourceRoots>
<multiReleaseOutput>true</multiReleaseOutput>
</configuration>
</execution>
</executions>
{code}
Similar to MCOMPILER-412 it would be useful and fix my issues if target/classes
is added to the compiler when doing this compiler execution.
