Hi Pierre,
The pom file works for me. Thank you.
I found out how to debug the code in in eclipse:
When I build the package using maven the maven put an annotation metadata
file into the generated jar file in the target folder:
org.apache.felix.dependencymanager.samples.annotation.hello.jar:META-INF/dependencymanager/org.apache.felix.dependencymanager.samples.annotation.hello
The content of the file is the following:
{"impl":"org.apache.felix.dependencymanager.samples.annotation.hello","start":"activate","type":"Component"}
But it doesn't add
dependencymanager/org.apache.felix.dependencymanager.samples.annotation.hello
into the META-INF folder of the project. (I don't know why though?!)
If I manually copy the above file from the jar file into the
META-INF/dependencymanager/ folder of the project, then the corresponding
service starts and eclipse can debug it.
**A new Question**:
Everytime I modify the annotation in a source file I have to run the "mvn
package" to create the target jar file and then copy the contents of
META-INF/dependencymanager/* form the jar file into the
META-INF/dependencymanager/ folder in the project. Is there a way to make
it automatic?
Thanks,
Mohica
