[jira] [Comment Edited] (MCOMPILER-367) Plugin should output

[ https://issues.apache.org/jira/browse/MCOMPILER-367?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16713697#comment-16713697 ]

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 C:\Users\Gili\Documents\3rdparty\testcase\target\classes
[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 javac includes "[module]". This indicates that "-Xlint:-module" will suppress this warning. I am expecting maven-plugin-compiler to show this information in its output.

> 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.
