I need to write a goal to invoke the main() method of a class in my
Maven project. Following suggestions in a recent thread on this list, I
am attempting this with the <ant:java/> tag. The problem I am having is
with the classpath, which needs to include the project's dependencies.
First I tried to use ${maven.dependency.classpath}, like so:
<goal name="perfmon:run">
<echo>maven.dependency.classpath=${maven.dependency.classpath}</echo>
<ant:java jar="${basedir}/target/perfmon-0.1.jar" fork="true">
<ant:classpath>
<ant:path path="${maven.dependency.classpath}"/>
</ant:classpath>
</ant:java>
</goal>
...which fails because apparently maven.dependency.classpath is not set
(according to the <echo/> tag). My second attempt was to hardcode the
necessary dependencies, but this fails for a different reason:
<goal name="perfmon:run">
<ant:java
jar="${basedir}/target/perfmon-0.1.jar"
fork="true">
<ant:classpath>
<ant:pathelement
location="${maven.repo.local}\springframework\jars\spring-1.0.jar"/>
</ant:classpath>
</ant:java>
</goal>
>From 'maven -X perfmon:run', this appears to construct the correct
arguments:
[java] [DEBUG] Execute:Java13CommandLauncher: Executing 'java.exe'
with arguments:
'-classpath'
'C:\Documents and
Settings\dcparsons\.maven\repository\springframework\jars\spring-1.0.jar
'
'-jar'
'C:\p4\dev\ims\test\perfmon\target\perfmon-0.1.jar'
However, I still see
[java] java.lang.NoClassDefFoundError:
org/springframework/beans/factory/xml/XmlBeanFactory
Any ideas? I'm running Maven 1.0RC2, under Windows. Is it having
trouble with the spaces in my maven.repo.local ("C:\Documents and
Settings\dcparsons\.maven\repository")? I've tried many variations on
constructing the path, like refids and fileSets, etc., but the behaviour
is the same: no ${maven.dependency.classpath}, and no class found.
