Flex .swc build using org.sonatype.flexmojos is failing

I am trying to create and build a flex library project (.swc) using maven 2 firsttime. I am able to create directory structure but build is failing.

My maven settings are : Maven version : apache-maven-3.0.2

1. mvn archetype:generate -DarchetypeGroupId=org.sonatype.flexmojos -DarchetypeArtifactId=flexmojos-archetypes-library -DarchetypeVersion=3.8 -DgroupId=com.test -DartifactId=sampleflexproject2 –e

This created the basic project skeleton as per my need.

1. mvn cl开发者_如何学JAVAean install –e –X

I get below exception while executing this command.

Do you foresee any obvious issue in this ?

Please post a simplified version of the POM.

The issue seems to be though that you are missing some configuration for the flexmojos-maven-plugin. It is complaining that the goal default-compile-swc has no output property defined.

Take a look at your plugin definition:

<plugin>
   <groupId>org.sonatype.flexmojos</groupId>
    <artifactId>flexmojos-maven-plugin</artifactId>
    <version>4.0-pre-alpha-1</version>
    <configuration>
      <output>${basedir}/target/sampleflexproject2.swf</output>
    </configuration>
</plugin>

That though alone will probably not be sufficient for a successful build.

Take a look https://repository.sonatype.org/content/sites/maven-sites/flexmojos/4.0-RC1/compile-swc-mojo.html for more information on what should be set in the configuration block.
