[jira] Created: (MPECLIPSE-103) Allow to skip dependencies from being included in .classpath file
Allow to skip dependencies from being included in .classpath file
-----------------------------------------------------------------
Key: MPECLIPSE-103
URL: http://jira.codehaus.org/browse/MPECLIPSE-103
Project: maven-eclipse-plugin
Type: New Feature
Versions: 1.9
Reporter: Werner Schulz
Need a means to specify that some maven dependencies are NOT included in the generated .classpath file.
Reason: Maven builds a project. This may include generating source via castor, InjectJ, etc.
Once the source code is generated, the generated source may not depend on the various jars that helped generate it.
That means, the Eclipse project should not depend on these jars. Currently, it is not possible to exclude these jars.
Can you add an additional property, like <eclipse.classpath.include>no</eclipse.classpath.include>, which will
not add the dependency to the generated classpath file.

[jira] Commented: (MPECLIPSE-103) Allow to skip dependencies from being included in .classpath file

-----------------------------------------
Yes, the dependencies listed in the project are all included in the Eclipse classpath file.
>From the Maven Eclipse Plugin documentation (see http://maven.apache.org/reference/plugins/eclipse/goals.html):
Goal: eclipse:generate-classpath
Description: Generates a .classpath file for the eclipse project with classpath entries for
1. the build source directory
2. the build unit test source directory
3. the JRE being used
4. the appropriate version of JUnit
5. each Maven project dependency
6. an output directory for compiled code: target\classes
7. any .zip source archives
The problem is item 5.
In my project, we generate some enumerations using Castor (using xerces-2.4). The generated
code is completely independent of XML or Castor.
The generated enumerations are needed in code that also accesses some proprietary stuff
which relies on an older version of xerces. Suddenly, Eclipse gets confused because the required
presence of castor and xerces dependencies in the project file (castor plugin doesn't seem to find
the necessary jars on its own!?) conflict with dependencies from other code bits.
This is an example where build and development dependency requirements are different but this
is not recognised by the eclipse plugin.

-------------------------------------------
I don't see how this can happen as the dependencies used to generate the source code will be dependencies of the plugin, not the project. Are you sure that this is what actually is happening?

If I understood correclty, you added the castor dependency in order to generate source code: the castor dependency, however, should not be a project dependency but a plugin dependency. For example this should work if you are using the maven castor plugin at http://maven.apache.org/maven-1.x/reference/plugins/castor/index.html (do you?).
If you are using a custom ant task you will need castor and xerces in the classpath, but this is not the recommended way.
First of all, castor will be in the classpath used by maven when executing tests, and this is the same situation you are seeing in eclipse (so, it SHOULD fail in eclipse if it fails with maven).
As a solution you should:
- use a plugin to generate sources and, if such plugin doesn't exist, extract your code from maven.xml and put it in a plugin (recommended)
- manually modify the classpath before calling the ant task used to generate sources, removing the castor jar from project.xml
