Issues building Kura from source in Eclipse [message #1567776]

Hey guys,

I'm trying to build Kura from the source, following instructions here

wiki.eclipse.org/Kura/Getting_Started

I am seeing two problems

first, when I run the emulator, I am getting that kind of message, with classNotFound exception
!ENTRY org.eclipse.kura.deployment.customizer 4 0 2015-01-16 10:00:30.583

Something strange as well ... when I make changes to the Java code, it seems that the code does not get recompiled, even after Maven | udpate project.

I noticed that some of the projects have only the M(aven) icon, whereas others are both M(aven) and J(ava)...

Did somebody ran into those issues as well?

Thanks
Regis

PS
another detail - I had to restructure some of the packages under org.eclipse.soda.dk as the comm package was missing.

Hello Regis,

Your last statement is concerning:

"I had to restructure some of the packages under org.eclipse.soda.dk as the comm package was missing."

There shouldn't be any missing packages. After cloning the repository, did you perform a full Maven build? If so, where were you seeing this error?

mvn -f target-platform/pom.xml clean install
mvn -f kura/manifest_pom.xml clean install -Dmaven.test.skip=true
mvn -f kura/pom_pom.xml clean install -Dmaven.test.skip=true -Pweb

When importing into Eclipse, you only imported the projects from kura/kura, correct? You cannot import kura/target-platform as this would confuse the dependency resolver.

Thanks,
--Dave

I am also having problems building in eclipse. Followed all steps in getting started and built the source with-out errors. But It will not build in eclipse.

Hi Jeff,

Were you able to run the Maven commands successfully? I am assuming so or you would have many more errors in your workspace. The PDE development environment can be a little finicky. On the projects where you are seeing errors, try right clicking on the project name and selecting: Maven -> Update Project... . On the resulting screen select OK. If this doesn't resolve the errors let me know.

Thanks,

Thanks for the response Dave.

I tried that, and have done reinstalls. The only build message that looks suspicious after "mvn clean install" is:

Are these warnings normal?

Hallo Jeff,
The "Non-Resolvable" parent pom error is due to the wrong version number in the pom.xml file.
Change the version tag in org.eclipse.kura.qa/pom.xm and org.eclipse.kura.test.helloworld/pom.xml

	<parent>
		<groupId>org.eclipse.kura</groupId>
		<artifactId>kura</artifactId>
		<version>1.2.0-SNAPSHOT</version>
		<relativePath>../manifest_pom.xml</relativePath>
	</parent>

Regards,
Jishnu
