Problem with DeclarativeServices meta generation out of SCR annotations.

[abara]

We are using the latest version of Fuse IDE to build a simple project where DeclarativeServices framework is used with org.apache.felix.scr.generator v1.1.4 for the component to be declared with use of annotations.

We are using next URL as an example: http://felix.apache.org/site/apache-felix-maven-scr-plugin-use.html

The problem with pom.xml we can not resolve:

Plugin execution not covered by lifecycle configuration: org.apache.felix:maven-scr-plugin:1.7.4:scr (execution: generate-scr-scrdescriptor, phase: process-classes)

pom.xml     

line 66

Maven Project Build Lifecycle Mapping Problem

I have attached pom file (and relevant parent pom).

We tried to clean project / refresh project / updated dependencies: no help.

It looks like something stupidly simple we are missing here....

Please help!

Hi,

this error comes from m2e which does not handle your scr plugin. So we need to define what to do with that plugin within the lifecycle mapping.

Try to add the following to your pom.xml file:

Hope that helps with your problem.

Lars,

Thank you for quick reply!

Upon pom.xml extension we still have the same issue

An updated pom.xml is attached.

Thank you

[lhein]

Are you sure that it is exactly the same issue? Could you post a stack or problem details info here?

Maven Project Build Lifecycle Mapping Problem

Thats really odd. Usually it should fix the problem. Could you rebuild it via mvn clean install and then reimport into Eclipse? (just to be sure)

[abara]

Result seems to be quite inconclusive: at some point I was able to get rid of the initial problem, but at this point FuseIDE (Eclipse) itself starts misbehaving:

• Errors occurred during the build. Errors running builder 'Maven Project Builder' on project 'DbConfigMng'. java.lang.NullPointerException *

This happened after I moved "pluginManagement" tag under "build" tag as it was suggested here: http://maven.apache.org/pom.html#Plugin_Management

It looks like even "clean" on the project does not help any longer, so I will re-assemble from the clean slate in minimal form and will check again...

Thank you

[lhein]

If you are fine with it you can also send me your zipped project so I can have a look at the problem.

[abara]

Upon project re-assembly, the original problem was positively RESOLVED (although, as newcomers to the technology we are struggling through other baby-steps).

Thank you!

[lhein]

Good to hear that it works out now for you. Please let us know if you encounter other problems. We are happy to help you solve your problems.

Lars,

It looks like we were able to get past compilation, but not really to use the service...

I'm providing a reduced samples in the file attached.

Hello1Service is using SCR plugin to declare and publish service.

Hello1Camel is creating a bean using the service and then uses bean in camel route.

On the surface:

18:40:14,219 | INFO  | rint Extender: 3 | BlueprintContainerImpl           | ?                                   ? | 10 - org.apache.aries.blueprint - 0.3.1 | Bundle com.videonext.tests.Hello1Camel is waiting for dependencies

smx@root> osgi:list|grep Hello

Hello1Service OSGi Bundle (0.0.1.SNAPSHOT)

Hello1Camel Blueprint Route (1.0.0.SNAPSHOT)

When looking deeper into Hello1Service assembled bundle:

afomenko:0 afomenko$ cat META-INF/MANIFEST.MF

Manifest-Version: 1.0

Bnd-LastModified: 1342463910466

Build-Jdk: 1.6.0_33

Built-By: afomenko

Bundle-ManifestVersion: 2

Bundle-Name: Hello1Service OSGi Bundle

Bundle-SymbolicName: com.videonext.tests.Hello1Service

Bundle-Version: 0.0.1.SNAPSHOT

Created-By: Apache Maven Bundle Plugin

Export-Package: com.videonext.tests.Hello1Service;version="0.0.1.SNAPSHO

T",com.videonext.tests.Hello1Service.Impl;uses:="com.videonext.tests.He

llo1Service";version="0.0.1.SNAPSHOT"

Import-Package: org.osgi.service.blueprint;version="[1.0.0,2.0.0)"

Service-Component: OSGI-INF/serviceComponents.xml

Tool: Bnd-1.50.0

afomenko:0 afomenko$ cat OSGI-INF/serviceComponents.xml

It looks like maven-plugin is ignoring export directive not to export "Impl" packages, but this is not a biggest issue.

The bigger one is: Hello1Camel is waiting forever to discover service which should have been essentially declared by Hello1Service exported configuration. Not sure where to go next from here. Please help!

thank you,

[abara]

Mistake from our side: we thought that upon sample successful compilation the rest would work, but apparently we still have the issue... Please see reply to last message for the problem description
