Generation of eclipse projects requires that reactor projects have installed jars

Description

« Hide

Most reactor actions work without requiring projects in the hierachy to have installed jars. eg, You can compile and test the hierarchy using only the project target directories. However, when generating eclipse projects, the plugin will fail if a dependent project in the hierarchy does not have its jar installed. (Note, that if the jar /is/ installed, a direct project reference /will/ be defined in the .classpath – ie, the project installed jar is never actually used.)

The title should be :
eclipse:eclipse requires target/classes directories present for project references.
see relative http://jira.codehaus.org/browse/MECLIPSE-67.

I have a probably related trouble.
My root pom contains modules :

accommons-tools (version 2.4-SNAPSHOT)
accommons-prefs (version 1.6-SNAPSHOT)
accommons-cache (version 2.5-SNAPSHOT)
split-tars (1.6-SNAPSHOT)

accommons-cache depends on : accommons-tools-2.3 and accommons-prefs-1.5
split-tars depends on accommons-tools-2.3, accommons-prefs-1.5 and accommons-cache-2.5-SNAPSHOT
In the root folder, I run : mvn compile eclipse:clean eclipse:eclipse
In accommons-cache, my .classpath contains :
<classpathentry kind="var" path="M2_REPO/C:/projets/accommons-libs/accommons-prefs/target/classes"/>
<classpathentry kind="var" path="M2_REPO/C:/projets/accommons-libs/accommons-tools/target/classes"/>

In split-tars folder, my .classpath contains :
<classpathentry kind="var" path="M2_REPO/C:/projets/accommons-libs/accommons-prefs/target/classes"/>
<classpathentry kind="var" path="M2_REPO/C:/projets/accommons-libs/accommons-tools/target/classes"/>

and a good :
<classpathentry kind="src" path="/accommons-cache"/>

I don't know if it's relative to this issue

fix in svn for 2.2.
The plugin now does a manual artifact resolution and doesn't require reactor projects to be installed anymore.
