David M. Lloyd commented on MCOMPILER-285:
------------------------------------------
Looks like {{-Xmodule}} has gone away as of April 19 (8178012). Builds of
OpenJDK after this time fail in maven-compiler-plugin for test sources:

> Support test-compile for JDK 9 build b148+
> ------------------------------------------
>
> Key: MCOMPILER-285
> URL: https://issues.apache.org/jira/browse/MCOMPILER-285
> Project: Maven Compiler Plugin
> Issue Type: Improvement
> Affects Versions: 3.6.0
> Reporter: Robert Scholte
> Assignee: Robert Scholte
> Fix For: 3.6.1
>
>
> {quote}
> JDK 9 build b148 includes an important Refresh of the module system.
> This refresh includes a disruptive change that is important to understand.
> For those that have been trying out modules with regular JDK 9 builds then be
> aware that `requires public` changes to `requires transitive`. In addition,
> the binary representation of the module declaration (module-info.class) has
> changed so that you need to recompile any modules that were compiled with
> previous JDK 9 builds.
> {quote}
> To be able to compile the test sources, you must specify the module name (i.e
> {{-Xmodule:the.module.name}}). This information is already available in
> {{src/main/java/module-info.java}}, so no need to ask for it again. Due to
> the change of the binary representation the original trick wiith
> ASM-6.0_ALPHA doesn't work anymore.
> We're going to add a second parser based on QDox, which doesn't parse the
> class file but the source file. This way we have to options to extract the
> module name.
