Objet : Re: [m2e-users] Issue with maven install of a product Eclipse
 
 
 
Hi Vincent !
Thank you to answer me … but if I change the packaging for eclipse-repository in my pom product I’ve this error :
Unknown packaging: eclipse-repository
 
 
Hi,
Maybe you need to put eclipse-repository instead of pom in your product pom.xml file
packaging.
 
 
 
Hello !
 
I’m a newbie with Maven.
I’ve some Eclipse plugins which are installed under a CDT Eclipse.
 
I wanted to use Maven …
J
 
I’ve done already the “install” of Update site of my plugins with maven technology and it works very fine !
 
I’ve added a product to make my branding, so I’ve a plugin product and its feature to generate my Eclipse and it’s ok.
Now I want to do the same with maven.
 
So I added
a pom
to my
product
plugin and
a
pom
to the
associated
feature, see the poms below:
Product pom :

I’ve this issue :
Caused by: java.lang.IllegalStateException: Tycho build extension not configured for MavenProject: pouet.workbench:pouet.product:1.0.0-SNAPSHOT
 @ C:\Users\burguera\TestSWMavensousKepler\pouet.product\pom.xml
at org.eclipse.tycho.core.utils.TychoProjectUtils.getTargetPlatform(TychoProjectUtils.java:63)
at org.eclipse.tycho.p2.facade.RepositoryReferenceTool.addTargetPlatformRepository(RepositoryReferenceTool.java:116)
...
 
I looked in the code of Tycho:
[CODE]
public
static TargetPlatform getTargetPlatform(MavenProject
 project) {
        TargetPlatform targetPlatform = (TargetPlatform) project.getContextValue(TychoConstants.CTX_TARGET_PLATFORM);
       
if (targetPlatform ==
null) {
           
throw
new IllegalStateException(TYCHO_NOT_CONFIGURED
 + project.toString());
        }
       
return targetPlatform;
    }
[/CODE]
 
Where CTX_TARGET_PLATFORM = targetPlatform
 
I don’t understand because I’ve a target platform define like this :
<repository>
< id>eclipse-kepler</id>
< layout>p2</layout>
< url>http://download.eclipse.org/releases/kepler</url>
< /repository>
 
I really don’t understand where is the trouble ???
Any idea ?
 
Thank you !
Chris
