Maven Ant Task problem when used with Ant 1.7.0
Hi,
I have a problem when using the maven ant task 2.0.4 with Ant 1.7.0.
The fileset created by the <maven:dependencies> task raises a
NullPointerException when used in the Ant <pathconvert> task.
Here an excerpt of the code which runs into this problem:
<!-- The Artifact to be looked for with the maven dependencies
task -->
<property name="artifact.groupid" value="junit"/>
<property name="artifact.id" value="junit"/>
<property name="artifact.version" value="3.8.1"/>
<!-- Try retrieving the artifact as a fileset -->
<maven:dependencies filesetId="dependency.files">
<dependency groupId="${artifact.groupid}"
artifactId="${artifact.id}"
version="${artifact.version}"/>
</maven:dependencies>
<!-- The following does not fail, showing that a fileset
reference has
actually been defined -->
<fail message="Reference 'dependency.files' has not been set or
is not a fileset reference.">
<condition>
<not><isreference refid="dependency.files"
type="fileset"/></not>
</condition>
</fail>
<!-- But the following task throws a NullPointerException -->
<pathconvert property="echo.dependency.files"
refid="dependency.files"/>
Are the maven ant task supposed to work with the last Ant 1.7.0 version ?
Any idea about what causes this problem ?

Thanks Kevin,
I have forwarded the previous mail completed with the full stack trace
to the ant dev list.

Hi,
Just a little update for those who may encounter this problem.
The ant dev team has investigated the problem and it appears the NPE was
raised because the Ant project was not set on the fileset created by
the "maven:dependencies" task.
The Ant code has been fixed to avoid raising an NPE is such a case.
Thanks to Kevin and Matt for the help.

RE Quick: because it was my change that triggered the
error in the first place, even though all I really did
was uncover their error. :)

I have checked in code to fix this. Those
experiencing the problem might want to test against a
build from SVN HEAD to verify the problem is fixed for
them. It wouldn't hurt to remind the Maven folks to
set the Project instance on artifacts they create,
either.

I've got it. It is indeed a case of the Maven code
not having set Project references on their artifacts.
PITA, but not the end of the world. The simplified
pathconvert code triggers the problem. My simple
testcase is:
<project>
<fileset id="fs" dir="${basedir}" />
<script language="beanshell">
fs.setProject(null);
</script>
<pathconvert refid="fs" />
</project>
which triggers the NPE in AbstractFileSet. I am
testing a fix now.

It looks like it is some strange stuff with
path through the code that just avoids an NPE in ant.1.6.5.
On ant 1.6.5 with the following file and the maven jar in lib,
the first echo works but the second echo fails:
<project name="test-maven" default="test"
xmlns:maven="antlib:org.apache.maven.artifact.ant">
<target name="test">
<typedef
uri="antlib:org.apache.maven.artifact.ant"
resource="org/apache/maven/artifact/ant/antlib.xml"
>
<classpath>
<fileset dir="lib" includes="*.jar"/>
</classpath>
</typedef>
<echo>Here</echo>
<property name="artifact.groupid" value="junit"/>
<property name="artifact.id" value="junit"/>
<property name="artifact.version" value="3.8.1"/>
<setproxy proxyhost="${proxy}" proxyport="8000"/>
<maven:dependencies filesetId="dependency.files">
<dependency groupId="${artifact.groupid}"
artifactId="${artifact.id}"
version="${artifact.version}"/>
</maven:dependencies>
<pathconvert property="echo.dependency.files"
refid="dependency.files"/>
<echo>${echo.dependency.files}</echo> <!-- 1 -->
<echo>${toString:dependency.files}</echo> <!-- 2 -->
</target>
</project>
I am not sure how to fix this in ant.

Re: Maven Ant Task problem when used with Ant 1.7.0
Posted by Matt Benson <gu...@yahoo.com>.
Sorry... to go farther down the stacktrace, I should
correct myself: it appears that the Maven guys don't
set a project on their fileset when they create it, or
something. So it's a bug for them, but possibly a
regression for Ant after all, if you want to look at
it that way.

Re: Maven Ant Task problem when used with Ant 1.7.0
Posted by Matt Benson <gu...@yahoo.com>.
That looks like a bug in the Maven task. The only way
for an NPE to be triggered here would seem to indicate
the task passed null as the project argument to
getDirectoryScanner(). Looking at Ant 1.6.5's code it
appears that the same exception would be thrown,
however, so I am confused how this problem only showed
up with Ant 1.7.0.

Maven Ant Task problem when used with Ant 1.7.0
Posted by Loic Jay <Lo...@Sun.COM>.
Hi,
I have submitted the following problem to the Maven mailing list which
redirected me to this Ant mailing list.
The problem occurs when I use the maven ant task 2.0.4 with Ant 1.7.0.
The fileset created by the <maven:dependencies> task raises a
NullPointerException when used in the Ant <pathconvert> task.
The following code :
<!-- The Artifact to be looked for with the maven dependencies
task -->
<property name="artifact.groupid" value="junit"/>
<property name="artifact.id" value="junit"/>
<property name="artifact.version" value="3.8.1"/>
<!-- Try retrieving the artifact as a fileset -->
<maven:dependencies filesetId="dependency.files">
<dependency groupId="${artifact.groupid}"
artifactId="${artifact.id}"
version="${artifact.version}"/>
</maven:dependencies>
<!-- The following does not fail, showing that a fileset
reference has
actually been defined -->
<fail message="Reference 'dependency.files' has not been set or
is not a fileset reference.">
<condition>
<not><isreference refid="dependency.files"
type="fileset"/></not>
</condition>
</fail>
<!-- But the following task throws a NullPointerException -->
<pathconvert property="echo.dependency.files"
refid="dependency.files"/>
Raises the following NullPointerException:

Any idea if this is an incompatibility introduced with Ant 1.7.0 ?
Thanks

Ant 1.7 introduced the concept of ResourceCollections, this code would
have affected filesets, but I cannot diagnose the problem further
without a full stack trace from you NullPointerException.
Would you post this to the ant dev list : dev@ant.apache.org
Thanks
