Maven Dependencies for Spring DM IntegrationTests

**DavidBull** · Dec 10th, 2008, 05:28 AM

Hello,

I've been trying to configure an integration test using maven 2.0.7 and Eclipse Ganymede (4.3.1): at this stage I am simply trying to verify the framework (Chapter 9 of the reference guide, 9.2.1).

This works successfully with the following dependencies:

Code:

<dependency>  
     <groupId>org.springframework.osgi</groupId>
     <artifactId>spring-osgi-test</artifactId>
     <version>1.0</version>
     <scope>test</scope>
</dependency>
<dependency>
     <groupId>org.eclipse.osgi</groupId>
     <artifactId>org.eclipse.osgi</artifactId>
     <version>3.2.2</version>
     <type>jar</type>
     <scope>provided</scope>
</dependency>
<dependency>
     <groupId>org.easymock</groupId>
     <artifactId>easymock</artifactId>
     <version>2.3</version>
     <scope>test</scope>
</dependency>
<dependency>
    <groupId>junit</groupId>
    <artifactId>junit</artifactId>
    <version>3.8.2</version>
</dependency>

but if I try to upgrade spring-osgi-test to 1.1.2 (or 1.1.0/1.1.1) I get the following error:

Code:

org.osgi.framework.BundleException: The bundle could not be resolved. 
Reason: Missing Constraint: Import-Package: org.slf4j.impl; version="1.5.0"

I asssume this means that I have a dependency missing but cannot find a definitive answer as to what this is (I have been down several blind alleys which lead to other problems)

Any help or suggestions would be gratefully received

You need this dependency :

Code:

<dependency> 
<groupId>org.slf4j</groupId>  <artifactId>com.springsource.slf4j.log4j</artifactId>
<version>1.5.6</version>
</dependency>

+

its required dependencies:

Bundle Name Bundle Symbolic Name Version
Apache Log4J com.springsource.org.apache.log4j 1.2.15
SLF4J API com.springsource.slf4j.api 1.5.6
SLF4J Jakarta Commons Logging Binding com.springsource.slf4j.jcl 1.5.6
Apache Commons Logging com.springsource.org.apache.commons.logging 1.1.1

I am also beginner in Spring DM server integration tests. I have run tests in same manner as described in chapter 9 and I get weird error:

Code:

16:16:16,125 DEBUG SimpleOsgiTest:208 - Looking for Spring/OSGi powered bundles to wait for...
16:16:16,140 DEBUG SimpleOsgiTest:377 - Caught exception starting up

16:16:16,156  INFO SimpleOsgiTest:491 - Shutting down OSGi platform

This means some problems with running Junit activator.
I am using the following bundles:

Code:

"org.aopalliance, com.springsource.org.aopalliance, 1.0.0",
"org.objectweb.asm, com.springsource.org.objectweb.asm, 2.2.3",
"org.junit, com.springsource.junit, 3.8.2",
"org.slf4j, com.springsource.slf4j.api, 1.5.0",
"org.slf4j, com.springsource.slf4j.log4j, 1.5.0",
"org.slf4j, com.springsource.slf4j.jcl, 1.5.6",
"org.slf4j, com.springsource.slf4j.org.apache.commons.logging, 1.5.0",
"org.springframework, org.springframework.aop, 2.5.5.A",
"org.springframework, org.springframework.beans, 2.5.5.A",
"org.springframework, org.springframework.context, 2.5.5.A",
"org.springframework, org.springframework.core, 2.5.5.A",
"org.springframework, org.springframework.test, 2.5.5.A",	
"org.springframework.osgi,log4j.osgi,1.2.15-SNAPSHOT",
"org.springframework.osgi,spring-osgi-annotation,1.0",
"org.springframework.osgi, org.springframework.osgi.extender, 1.1.2.B",
"org.springframework.osgi, org.springframework.osgi.core, 1.1.2.B",
"org.springframework.osgi, org.springframework.osgi.io, 1.1.2.B",
"org.springframework.osgi, org.springframework.osgi.test, 1.1.2.B",

BWT, has somebody simple workable example for running these tests?

I will be thankful for any good idea and suggestion.

integration test samples are provided with Spring OSGi distribution

**DavidBull** · Dec 10th, 2008, 09:54 AM

Thank you for your suggestion: unfortunately, when I tried this I still get the same "org.osgi.framework.BundleException: Missing Constraint: Import-Package: org.slf4j.impl; version="1.5.0" error

David, can you please raise an issue to track this down? As frederic mentioned, the distribution already provides several samples which you can use.
It might be that either our setup process automatically downloads an artifact that's missing from your repo. By the way, could you try Maven 2.0.9 and see whether that fixes your problem?
Thanks,

**Costin Leau** · Jan 4th, 2009, 04:13 AM

David, I've raised an issue myself (http://jira.springframework.org/browse/OSGI-691).
Cheers,

**Costin Leau** · Jan 4th, 2009, 04:17 AM

tushak, you seem to be using the 1.1.2.B versions - can you try the SourceForge (non-A,B) versions?
I've raised an issue to track this down here: http://jira.springframework.org/browse/OSGI-692

This being said, in the future, please start your own thread when reporting slightly different problems - linking is prefereable to 'thread hijacking'. Thanks.

**DavidBull** · Jan 5th, 2009, 05:27 AM

Costin,

I apologise for not replying sooner: I am pretty sure that I tried 2.0.9 as well but will try again with a clean workspace and attach a comment to the JIRA ticket

David, I've looked at the issue closer and the problem is that you've added only the SFL4J API - you also need the commons-logging adapter and log4j bridge (or whatever other logging implementation you want to use).
I've updated section 5.3 from the docs to better reflect the needed logging jars.

The jars you need are the following:

Code:

    <!-- commons-logging in slf4j wrapper -->
    <dependency>
      <groupId>org.slf4j</groupId>
      <artifactId>com.springsource.slf4j.org.apache.commons.logging</artifactId>
      <version>${slf4j.version}</version>
      <scope>provided</scope>
    </dependency>
    <dependency>
      <groupId>org.slf4j</groupId>
      <artifactId>com.springsource.slf4j.api</artifactId>
      <version>${slf4j.version}</version>
      <scope>provided</scope>
    </dependency>
    <dependency>
      <groupId>org.slf4j</groupId>
      <artifactId>com.springsource.slf4j.log4j</artifactId>
      <version>${slf4j.version}</version>
      <scope>provided</scope>
      <exclusions>
        <exclusion>
            <groupId>log4j</groupId>
            <artifactId>log4j</artifactId>
        </exclusion>
        <exclusion>
            <groupId>org.apache.log4j</groupId>
            <artifactId>com.springsource.org.apache.log4j</artifactId>
        </exclusion>
      </exclusions>
    </dependency>

Note that this is just the slf4j bit - you'll still have to add the log4j bit (or again, change that to a different implementation if you want).
Cheers,
