Subject [jira] Reopened: (MPIR-188) Maven constructs wrong classpath element
Date Mon, 05 Apr 2010 14:24:23 GMT


David Biesack reopened MPIR-188:

MPIR-146 is marked as fixed in 2.1 yet this defect still exists in 2.2.1.
I cannot reopen MPIR-146 so I'm opening this one instead. Also, MPIR-146 was
marked as a Blocker; perhaps this one should be also.

>                 URL:
>             Project: Maven 2.x Project Info Reports Plugin
>          Issue Type: Bug
>          Components: dependencies
>    Affects Versions: 2.1

> We run Maven 2 builds from Cruise Control; the projects each build with the same targets:
>   clean jar:test-jar site-deploy deploy
> Unfortunately, this causes the unit tests to run twice, once for site-deploy (surefire
reports) and once for deploy.
> Under 2.0.9 this was not a problem, but we recently switched to 2.2.1 and some tests
were failing
> because the test classpath constructed for the first set of test runs differs from the
classpath for the second.
> In the pom file, there is a dependency from the current project to both the normal jar
*and* the test jar of 
> another project:
>     <dependency>
>       <groupId></groupId>
>       <artifactId>sas.other</artifactId>
>       <version>1.0-SNAPSHOT</version>
>       <type>test-jar</type>
>       <scope>test</scope>
>     </dependency>
>   <dependency>
>       <groupId></groupId>
>       <artifactId>sas.other</artifactId>
>       <version>1.0-SNAPSHOT</version>
>     </dependency>
> The first test run contains
> [DEBUG]   /u/acladmin/.m2/repository/com/sas/other/sas.other/1.0-SNAPSHOT/sas.other-1.0-SNAPSHOT-tests.jar
> ...
> [DEBUG]   /u/acladmin/.m2/repository/com/sas/other/sas.other/1.0-SNAPSHOT/sas.other-1.0-SNAPSHOT.jar
> However, when we build with Maven 2.2.1, the classpath of the second test run is different:
> [DEBUG]   /u/acladmin/.m2/repository/com/sas/other/sas.other/1.0-SNAPSHOT/sas.other-1.0-SNAPSHOT.jar
> ...
> [DEBUG]   /u/acladmin/.m2/repository/com/sas/other/sas.other/1.0-SNAPSHOT/sas.other-1.0-SNAPSHOT.jar
> Because the classpath is missing a jar, the tests fail, and hence the entire build fails.
> If we run the targets separately
>   mvn clean deploy
>   mvn site-deploy
> then maven only runs the tests once per run, with the correct classpath, so the test
and the entire build passes.
> This looks like a regression between 2.0.9 and 2.2.1. Sorry, we did not install/test
other intermediate releases.
