Hi,
I am currently trying to use the maven-plugin-testing-harness for
testing a report plugin. Two questions came up so far:
1.) When I run the test, I receive the following exception:
java.lang.NullPointerException">java.lang.NullPointerException
at
org.apache.maven.artifact.resolver.DefaultArtifactResolver.resolve(De
faultArtifactResolver.java:100)
at
org.apache.maven.artifact.resolver.DefaultArtifactResolver.resolve(De
faultArtifactResolver.java:63)
at
org.codehaus.mojo.rat.RatReportMojo.getSkinArtifactFile(RatReportMojo
.java:124)
at
org.codehaus.mojo.rat.RatReportMojo.execute(RatReportMojo.java:209)
at
org.codehaus.mojo.rat.RatCheckMojoTest.testIt3(RatCheckMojoTest.java:
178)
The exception is caused by the fact, that I need to provide a
parameter
/**
* @parameter default-value="${localRepository}"
* @required
* @readonly
*/
private ArtifactRepository localRepository;
How do I creare this parameter? I suppose, it's an instance of
DefaultArtifactRepository,
but how do I configure it?
I'm pretty sure the testing harness can take care of expressions
${localRepository}... it may be because you put it in "default-value"
instead of "expression".
2.) My test POM currently contains the following section:
<build>
<plugins>
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>rat-maven-plugin</artifactId>
<version>0.1-SNAPSHOT</version>
<configuration/>
</plugin>
</plugins>
</build>
<reporting>
<plugins>
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>rat-maven-plugin</artifactId>
<version>0.1-SNAPSHOT</version>
<configuration/>
</plugin>
</plugins>
</reporting>
It seems, that the build section is required, although I would want
to use the
reporting section only, as in the actual POM which uses my report. Is
that
possible?
This is a bug... Please file this in jira and we'll have a look at it.
Thanks.
Thanks,
Jochen
