[MCOMPILER-514] Cant stack compiler plugin argument variations

**[Delany](https://issues.apache.org/jira/secure/ViewProfile.jspa?name=delany)** opened **[MCOMPILER-514](https://issues.apache.org/jira/browse/MCOMPILER-514?redirect=false)** and commented

This works

```java

  -Xlint:all,-processing
  -Xlint:all
  -XDcompilePolicy=byfile
  -Xplugin:ErrorProne
  -Xplugin:ErrorProne

```

But this

```java

  -Xlint:all,-processing
  -Xlint:all
  -XDcompilePolicy=byfile
  -Xplugin:ErrorProne
  -Xplugin:ErrorProne -XepDisableAllChecks

```

fails with this

```
[ERROR] org.apache.maven.cli.MavenCli - plug-in not found: ErrorProne
```

There is no problem stacking -Xlint argument variations, or stacking the -Xplugin argument (provided the argument is the same.) But it dies when the -Xplugin argument varies. Why should this be?

Use case? I have separate profiles for activating various errorprone bugpatterns. I want a default configuration in place unless I activate one of these profiles. I dont want to have to edit source code every time to check a different bugpattern.
