Running "mvn clean install" on the testcase results in:
{quote}[INFO] — maven-compiler-plugin:3.8.0:compile (default-compile) @
testcase —
[INFO] Changes detected - recompiling the module!
[INFO] Compiling 2 source files to

[WARNING]
/C:/Users/Gili/Documents/3rdparty/testcase/src/main/java/module-info.java:[2,32]
module not found: someOtherModule
{quote}
I then run the following compilation:
{{javac -d C:\Users\Gili\Documents\3rdparty\testcase\target\classes -classpath
C:\Users\Gili\Documents\3rdparty\testcase\target\classes; -sourcepath
C:\Users\Gili\Documents\3rdparty\testcase\src\main\java;C:\Users\Gili\Documents\3rdparty\testcase\target\generated-sources\annotations;
-s
C:\Users\Gili\Documents\3rdparty\testcase\target\generated-sources\annotations
-g -target 11 -source 11 -encoding UTF-8 com\company\SomeClass.java
module-info.java}}
I get:
{quote}module-info.java:2: warning: [module] module not found: someOtherModule
exports com.company to someOtherModule;
^
1 warning
{quote}
Notice that the javac output includes "[module]" at the beginning of the
warning message. This indicates that "-Xlint:-module" will suppress this
warning. I am expecting maven-plugin-compiler to show this information in its
output.

> Plugin should output information needed to suppress Xlint warnings
> ------------------------------------------------------------------

> Key: MCOMPILER-367
> URL: https://issues.apache.org/jira/browse/MCOMPILER-367
> Project: Maven Compiler Plugin
> Issue Type: Improvement
> Affects Versions: 3.8.0
> Reporter: Gili
> Priority: Major
> Attachments: testcase.zip
>
>
> I will attach a testcase showing the following problem.
> If you compile a project that has compiler warnings, javac's output indicates
> which Xlint option will suppress the warning. But when compiling the same
> code under this plugin, this vital information is suppressed so the user has
> a difficult time figuring out which option to use.
> Expected behavior: output should indicate which Xlint option corresponds to
> the warning.
