Description
I'm getting:
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) at org.apache.maven.plugin.compiler.CompilerMojo.execute (CompilerMojo.java:188) at org.apache.maven.plugin.DefaultBuildPluginManager.executeMojo (DefaultBuildPluginManager.java:134) at org.apache.maven.lifecycle.internal.MojoExecutor.execute (MojoExecutor.java:208) at org.apache.maven.lifecycle.internal.MojoExecutor.execute (MojoExecutor.java:154)
Appears to be caused by the exception handling assuming the 'cause' will be non-null:
line 244 is:
243 Throwable cause = pathException.getValue().getCause(); 244 while ( cause.getCause() != null ) 245 { 246 cause = cause.getCause(); 247 }
Clearly in some cases pathException.getValue().getCause() is returning null.
This occurs when I try to build a java 10 project using:
mvn deploy
I've narrowed the problem down to this dependancy:
<!-- https://mvnrepository.com/artifact/org.javamoney/moneta --> <dependency>
<groupId>org.javamoney</groupId>
<artifactId>moneta</artifactId>
<version>1.3</version>
<type>pom</type>
</dependency>
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:
