---------------------------------
Summary: Cannot find dependency in Ant plugin based on multiple
build scripts
Key: MNG-5263
URL: https://jira.codehaus.org/browse/MNG-5263
Project: Maven 2 & 3
Issue Type: Bug
Components: Plugin API
Affects Versions: 3.0.2
Environment: Windows XP
Reporter: Hebus Nimbus
I am trying to create a custom ant plugin for Maven, based on multiple build
scripts. There is a note in the documentation about it:
http://maven.apache.org/guides/plugin/guide-ant-plugin-development.html (see "A
Note on Multiple Build Scripts"), but I have not been able to make it work.
Here are the scripts:
<root>\src\main\scripts\A.build.xml
-----------------------------------
<project>
<import file="C.build.xml"/>
<target name="hello" depends="dependency">
<echo>Hello, World</echo>
</target>
</project>
<root>\src\main\scripts\A.mojos.xml
-----------------------------------
<pluginMetadata>
<mojos>
<mojo>
<goal>hello</goal>
<call>hello</call>
</mojo>
</mojos>
</pluginMetadata>
<root>\src\main\scripts\B.build.xml
-----------------------------------
<project>
<target name="hello">
<echo>Hello, World</echo>
</target>
</project>
<root>\src\main\scripts\B.mojos.xml
-----------------------------------
<pluginMetadata>
<mojos>
<mojo>
<goal>hello2</goal>
<call>hello</call>
</mojo>
</mojos>
</pluginMetadata>
<root>\src\main\scripts\C.build.xml
-----------------------------------
<project>
<target name="dependency">
<echo>This is the dependency</echo>
</target>
</project>
<root>\pom.xml

At the root level, I run "mvn clean install", which is successful.
Then I run "mvn org.myproject.plugins:hello-plugin:hello2", which is also
successful and produces the "Hello, World" output.
However, when running "mvn org.myproject.plugins:hello-plugin:hello", I get
this:

By looking at the error, the script is executed in a temporary folder, hence it
cannot find the imported C.build.xml.
