Hi Peter,
I would consider this as a Maven Archetype issue.
Regarding the properties, the MavenSession has a deprecated method
getExecutionProperties(), which is split up into getSystemProperties() and
getUserProperties(). When using the Invoker it doesn't make sense to add
SystemProperties (again), userProperties (-Dkey=value entries) should be
enough. But it could be I missed a usecase, which also implies there are
not enough integration tests.
AFAIK we're never creating a new ProjectBuildingRequest, we should be
using the original or a clone of it, so the suggestion to set both types
of properties seems weird.
If you can create a JIRA issue for ARCHETYPE with a small integration test
for the plugin, it shouldn't be so hard to fix it.
thanks,
Robert

Hi guys,
I'm writing here to ask what I have found is a bug or not. I have a
project
and I want to create an archetype out of it. So I use the following
command:
mvn archetype:create-from-project
-Darchetype.properties=src/main/resources/archetype.properties
It used to work fine with maven-archetype<=2.4 but now with 3.0 it fails
with:
Caused by: org.apache.maven.plugin.MojoFailureException: Error reading
parent POM of project: com.nemesis:bom:1.5.0.BUILD-SNAPSHOT
at
org.apache.maven.archetype.mojos.CreateArchetypeFromProjectMojo.execute(CreateArchetypeFromProjectMojo.java:269)
at
org.apache.maven.plugin.DefaultBuildPluginManager.executeMojo(DefaultBuildPluginManager.java:134)
at
org.apache.maven.lifecycle.internal.MojoExecutor.execute(MojoExecutor.java:207)
I started debugging and I found out that the problem is in this commit:
https://github.com/apache/maven-archetype/commit/624f9affdc27c8efe6443e03e89259dbe51d08dd
which migrates the plugin to Maven3.
Furthermore debugging and stacktrace analysis revealed this:
*[ERROR] Failed to determine Java version for profile
doclint-java8-disable
@ org.jboss:jboss-parent:19,
/home/petar/.m2/repository/org/jboss/jboss-parent/19/jboss-parent-19.pom,
line 746, column 15*
and indeed inside my parent pom.xml I have included the jboss bom like
this:
<dependency>
<groupId>org.drools</groupId>
<artifactId>drools-bom</artifactId>
<type>pom</type>
<version>${drools.version}</version>
<scope>import</scope>
</dependency>
which has a parent the jboss-parent.
Now if you debug further more in the maven-archetype-plugin you will see
here:
https://github.com/apache/maven-archetype/blob/master/archetype-common/src/main/java/org/apache/maven/archetype/creator/FilesetArchetypeCreator.java#L439
we create a new DefaultProjectBuildingRequest and don't set any system
properties to it
so it eventually gets passed down to maven-core which cannot find
"java.version"
system property (because there are no properties passed) and it adds the
error that I see.
Now I have a several questions: why have we left the
ProjectBuildingRequest
without system properties? Also the ProjectBuildingRequest has no
userProperties set - is this OK? I can fix the system properties with:
buildingRequest.setSystemProperties( System.getProperties() );
buildingRequest.setUserProperties( configurationProperties );
but is this correct?
