Hy List,
lets assume i have 3 Projects:
xx.yy.app.parent
xx.yy.app.module1
xx.yy.app.module2
.parent is Parent of both modules
--- cut ---
<parent>
<artifactId>xx.yy.app.parent</artifactId>
<groupId>xx.yy.app</groupId>
<version>1.0.0-SNAPSHOT</version>
</parent>
<modelVersion>4.0.0</modelVersion>
<groupId>xx.yy.app</groupId>
<artifactId>xx.yy.app.module1</artifactId>
<version>1.0.0-SNAPSHOT</version>
<name>Module 1</name>
--- cut ---
, in .parent the both modules are linked with:
--- cut ---
<modules>
<module>../xx.yy.app.module1</module>
<module>../xx.yy.app.module2</module>
</modules>
--- cut ---
Now i start "clean package" on Eclipse, my output is:
