Description

« Hide

line.separator does not resolve properly inside an ant task (using maven-antrun-plugin).

E.g., using the 2 attached files, running

ant

produces the following output

Buildfile: build.xml

echo:
     [echo] 
     [echo] line.separator: --
     [echo] --
     [echo] os.name: --Linux--
     [echo]         

BUILD SUCCESSFUL
Total time: 0 seconds

which is all okay, so far (new line is being shown on the echo line).

However, when using

mvn initialize

, we get the following output

[INFO] Scanning for projects...

I have two questions:

Why do I have to specify all the properties one-by-one while calling the target?
Why is the output for line.separator not what is expected?

This seems similar to my experience. I can't find any documentation or an issue that precisely captures my issue, but this entry is the closest. Adding my comment here rather than creating another issue.

I started prototyping delegation to an ant script by writing the ant tasks inline with the plugins configuration. Once that worked I extracted the ant code to a separate build.xml and delegated to it using the ant task as suggested in the plugin documentation: "...it's encouraged to move all your Ant tasks to a build.xml file and just call it from the POM using Ant's <ant/> task.".

Wanting to use Maven as the source of configuration I made heavy use of the Maven properties (project.build.sourceDirectory, project.build.outputDirectory, etc). The Maven property reference worked fine when I was using the inlined task but failed once it was extracted to a build.xml file. I was hoping that the Maven properties would be passed to the ant build transparently, or as long as the inhertiAll attribute was true. It surprised me that they weren't and that I'd have to essentially alias each value I needed, causing a lot of extra work.

Is it possible to correct this behavior? Am I just missing something?

Pardon my ignorance, I missed ~~MANTRUN-40~~ and ~~MANTRUN-64~~ which seem to describe my issue. (Learn to search JIRA istead of using google =)
