> NPE in CompilerMojo.preparePaths on exception

>
> Key: MCOMPILER-355
> URL: https://issues.apache.org/jira/browse/MCOMPILER-355
> Project: Maven Compiler Plugin
> Issue Type: Bug
> Environment: ubunutu 18.04.
> Reporter: Brett Sutton
> Priority: Major
>
> I'm getting:
>
> {code:java}
>
> Caused by: java.lang.NullPointerException
> at org.apache.maven.plugin.compiler.CompilerMojo.preparePaths (CompilerMojo.java:244)
> at org.apache.maven.plugin.compiler.AbstractCompilerMojo.execute (AbstractCompilerMojo.java:787)

> Appears to be caused by the exception handling assuming the 'cause' will be non-null:
> line 244 is:
> {code:java}
> 243 Throwable cause = pathException.getValue().getCause();
> 244 while ( cause.getCause() != null )
> 245 {
> 246 cause = cause.getCause();
> 247 }{code}
>
> Clearly in some cases pathException.getValue().getCause() is returning null.
> This occurs when I try to build a java 10 project using:
> {code:java}
> mvn deploy{code}
>
> I've narrowed the problem down to this dependancy:
> {code:java}
> <!-- https://mvnrepository.com/artifact/org.javamoney/moneta --> <dependency>
> <groupId>org.javamoney</groupId>
> <artifactId>moneta</artifactId>
> <version>1.3</version>
> <type>pom</type>
> </dependency>{code}
> If you remove the above dependency then the problem goes away.
> So there is likely to be two problems here. The initial NPE which should be easy to fix and then possibly the root cause of the exception.
> Full pom is:
> {code:java}
