Test Harness, how to wire a MavenProjectHelper

[Frank Wilson <fa...@gmail.com>]

Hi,

Please could someone explain how to wire a MavenProjectHelper into my
mojo using the test harness?

I try to wire it using the test pom, however it seems the
MavenProjectHelpers dependencies are not satisfied.

Here's the line in my test POM:

https://github.com/zenlambda/fabric8/blob/mule-enable_fabric_deploy/fabric8-maven-plugin/src/test/resources/unit/forked-project-attachments/mule-test/pom.xml#L38

Here is the test:

https://github.com/zenlambda/fabric8/blob/mule-enable_fabric_deploy/fabric8-maven-plugin/src/test/java/io/fabric8/maven/ForkedTestValidatorTest.java#L30

The mojo I am trying to execute fails here:

https://github.com/zenlambda/fabric8/blob/mule-enable_fabric_deploy/fabric8-maven-plugin/src/test/java/io/fabric8/maven/probes/AttachZipMojo.java#L52


Because of a null pointer exception here:

https://github.com/apache/maven/blob/maven-3.0.5/maven-core/src/main/java/org/apache/maven/project/DefaultMavenProjectHelper.java#L70

presumably because the requirement wasn't satisfied.

https://github.com/apache/maven/blob/maven-3.0.5/maven-core/src/main/java/org/apache/maven/project/DefaultMavenProjectHelper.java#L40

Stacktrace:

java.lang.NullPointerException

Why isn't plexus satisfying the requirement?

Thanks,

Frank
