maven2 - choose dependcies based on platform

today I run into an old friend. I was compiling my stuff happily under oxs and building eclipse plugins with maven2 and the psteclipse plugin, which I by now more or less rewrote and adapted to my project to perform as good as possible. Anyway, basically I encountered the issue that eclipse ships with different dependencies under osx/win32 and linux.

So promptly it fails to compile under linux...

solution for this problem?

maven2 profiles, your best friend for cross platform development. They actually allow you define dependencies based on the current platform.

Example for out case would be:


<profiles>
<profile>
<id>dev-windows</id>

<dependencies>
</dependencies>

<activation>
<activeByDefault>true</activeByDefault>
<os>
<family>windows</family>
</os>
</activation>
</profile>
<profile>
<id>dev-mac</id>
<dependencies>
<dependency>
<groupId>psteclipse</groupId>
<artifactId>org.eclipse.swt.cocoa.macosx</artifactId>
<version>3.5.1</version>
<scope>provided</scope>
</dependency>

</dependencies>

<activation>
<activeByDefault>false</activeByDefault>
<os>
<family>mac</family>
</os>
</activation>
</profile>
<profile>
<id>dev-linux</id>

<dependencies>
<dependency>
<groupId>psteclipse</groupId>
<artifactId>org.eclipse.swt.gtk.linux.x86</artifactId>
<version>3.5.1</version>
<scope>provided</scope>
</dependency>
</dependencies>

<activation>
<activeByDefault>false</activeByDefault>
<os>
<name>linux</name>
</os>
</activation>
</profile>
</profiles>


And sets a different library for osx and linux. Sweet!
