Find source jars and add them to the classpath when executing the GWT compiler
------------------------------------------------------------------------------
Key: MGWT-170
URL: http://jira.codehaus.org/browse/MGWT-170
Project: Maven 2.x GWT Plugin
Issue Type: Improvement
Affects Versions: 1.1
Reporter: Micah Whitacre
When dealing with multiple modules/projects[1], it would be nice to remove the
restriction that source code must be bundled inside of the final endstate. In
addition to making the endstates larger it also means making source code more
available than a developer/corporation desire. I started a discussion on the
GWT Community group[2] about what the requirements are for the GWT compiler.
I'd propose that instead of forcing endstates to include the source code you
make use of the Maven convention of using separate sources jars. In my testing
I've found that if I have Project A depends on a module represented by
ProjectB. If I configure B to produce the following 2 endstates:
ProjectB.jar
ProjectB-sources.jar
I can then configure Project A to have the following dependencies:
<dependency>
<groupId>org.foo</groupId>
<artifactId>projectB</artifactId>
<scope>compile</scope>
</dependency>
<dependency>
<groupId>org.foo</groupId>
<artifactId>projectB</artifactId>
<scope>provided</scope>
<classifier>sources</classifier>
</dependency>
This eliminates the need for the final endstates to include code and will also
make the GWT compiler happy. Additionally if the gwt-maven-plugin wanted to
make a developer's life really really easy it could download the source jars
automatically[3] and attach them to the classpath.
So the 2 things I propose are:
1. enhance the documentation to state the use of sources jars.
2. download the source jars automatically and use them to make the gwt compiler
happy.
