Exception when built from a aggregator pom at project root. #22

Closed vcottagiri closed 10 years ago

vcottagiri commented 10 years ago

Created a simple pom in the root folder (maven-xtext-example).

pom.xml

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>
    <groupId>my.mavenized.herolanguage</groupId>
    <artifactId>my.mavenized.herolanguage.module</artifactId>
    <packaging>pom</packaging>
    <name>${project.artifactId}</name>
    <version>1.0.0-SNAPSHOT</version>

    <modules>
        <module>my.mavenized.herolanguage.releng</module>
        <module>example-project</module>
    </modules>
</project>

During maven build from the root folder (ie without changing directory into releng) the MWE2 workflow fails to find the dsl projects build.properties and MANIFEST.MF.

It looks like the mwe2 build is dependent on the path from which it is triggered.

This is very inconvenient because typically maven projects are organized into many nested multi-module builds, this way building at the root of the project tree builds all projects in it.

Is there anything that can be adjusted in the mwe2 file or the pom to get this to work?

this has been solved in 2.5.1. I've upgraded the version numbers.
