Karl Heinz Marbaise commented on MCOMPILER-355:
-----------------------------------------------
I see that the output of {{mvn -version}} does not show the information about
the commit which it has been created off which should look like this:

Furthermore to fix an issue the first step is to reproduce it which is used as
a foundation for an integration test which currently does not work cause if I
use your examples:

Apart from that what looks strange to me is the output at the beginning:
{noformat}
WARNING: An illegal reflective access operation has occurred
WARNING: Illegal reflective access by
com.google.inject.internal.cglib.core.$ReflectUtils$1
(file:/usr/share/maven/lib/guice.jar) to method
java.lang.ClassLoader.defineClass(java.lang.String,byte[],int,int,java.security.ProtectionDomain)
WARNING: Please consider reporting this to the maintainers of
com.google.inject.internal.cglib.core.$ReflectUtils$1
WARNING: Use --illegal-access=warn to enable warnings of further illegal
reflective access operations
WARNING: All illegal access operations will be denied in a future release
{noformat}
Furthermore can you please run your build with {{mvn -X deploy}} and send me
the log output (If you like in private mail instead of attaching it here):
One more detail. The output shows an entry
{{file:/usr/share/maven/lib/guice.jar}} which is not of an original Apache
Maven download cause in Apache maven this looks like this:
{{/usr/local/maven/lib/guice-4.0-no_aop.jar}} which gives me the impression
that you are not using an original Apache Maven installation..
Can you please make a {{ls -al}} of {{ls -al /usr/shared/maven/lib}} directory ?
Apart from that I would suggest to download Apache Maven from here:
https://maven.apache.org/download.cgi and retest with the original
installation...
> 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

> 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}
