question about maven dependency

i loaded the maven project in eclipse then found sth wrong with pom.xml file, when i clicked the 'overview' tab(m2eclipse), it said: 

Failed to read artifact descriptor for commons-logging:commons-logging:jar:1.1.2-SNAPSHOT

when i clicked the dependency hierarchy tab, it showed 'Project read error', however i have no problem to run 'mvn dependency:tree' from command line and can see there is a dependency on commons-logging:

commons-logging:commons-logging:jar:1.1.1:compile

just don't understand where the commons-logging 1.1.2-SNAPSHOT comes from. any idea ? Thanks.

In order to determine where the dependency commons-logging comes from (even without the .pom editor and its dependency editor) open the console and execute the following command:

mvn dependency:tree -Dverbose -Dincludes=commons-logging

This will show all dependencies of commons-logging.

I looked through the dependency tree, but did not find any reference to 1.1.2-SNAPSHOT.

Finally, adding the following dependency to my pom.xml solved the problem:

    <dependency>
        <groupId>commons-logging</groupId>
        <artifactId>commons-logging</artifactId>
        <version>1.1.2-SNAPSHOT</version>
    </dependency>

eclipse by default does not use the same maven installation as your command line. Depending on your m2eclipse version it might use an embedded maven snaphsot (with strange behaviour). Check

eclipse -> Window -> Preferences -> Maven -> Installations

and add your external maven installation (prefer current version 3.0.3) to the list and use this as default.

It's most likely coming into your project transitively. You can check the "Dependency Hierarchy" section of your pom editor in eclipse and see where it's coming from (search for commons-logging in the right top box). Also, I cannot see a 1.1.2-SNAPSHOT version of commons-logging on central so most likely someone has made a mistake in a dependency pom.
