I am trying to build an android project with maven, but maven doesn't like the Qname class:

[INFO] 
[INFO] trouble processing "javax/xml/namespace/QName.class":
[INFO] 
[INFO] Ill-advised or mistaken usage of a core class (java.* or javax.*)
[INFO] when not building a core library.

This problem only started occurring when I brought in a separate apklib file:

    <dependency>
        <groupId>cocos2d_android</groupId>
        <artifactId>cocos2d_android</artifactId>
        <version>1.0.0-SNAPSHOT</version>
        <type>apklib</type>
    </dependency>

It appears the QName class only appears in my dependencies in the xpp3 jarfile which, as far as I can tell, only appears in this dependency:

<dependency>
    <groupId>com.google.android</groupId>
    <artifactId>android</artifactId>
    <version>${android-version}</version>
</dependency>

I tried using the exclusion tag to get Maven to play nice with it, but the xmlpullparser class is being used in code in my project so I get a class not found error when I exclude it.

For completeness, here's my full dependency list:

<dependencies>
    <dependency>
        <groupId>com.google.android</groupId>
        <artifactId>android</artifactId>
        <version>${android-version}</version>
    </dependency>
    <dependency>
        <groupId>org.codehaus.jackson</groupId>
        <artifactId>jackson-jaxrs</artifactId>
        <version>${jacksonVersion}</version>
    </dependency>
    <dependency>
        <groupId>org.springframework.android</groupId>
        <artifactId>spring-android-rest-template</artifactId>
        <version>${spring-android-version}</version>
    </dependency>
     <dependency>
        <groupId>com.codeslap</groupId>
        <artifactId>android-facebook</artifactId>
        <version>1.5</version>
    </dependency>
    <dependency>
        <groupId>cocos2d_android</groupId>
        <artifactId>cocos2d_android</artifactId>
        <version>1.0.0-SNAPSHOT</version>
        <type>apklib</type>
    </dependency>
    <dependency>
     <groupId>org.twitter4j</groupId>
     <artifactId>twitter4j-core</artifactId>
     <version>[2.2,)</version>
    </dependency>
</dependencies>

I've seen other questions talking about this being imported in other google data apis, but obviously I'm not using those here - can someone explain why Maven is complaining about this class that's only part of the main google android apis?

So you have tried answer here, and get xmlpullparser class not found error, right - yorkw 2012-04-03 23:10

In case you reference com.google.android:android as dependency, do not forget to set provided scope - otherwise plugin will try to pack it into resulting apk

you're right. I used to have that scope set but in hacking about I removed it and then for some reason thought provided was the default. This did it. Thanks - Bry M. 2012-04-04 14:54

You cannot build Android applications that import JAR files that use java.* or javax.* packages. The cocos2d_android dependency either contains a copy of this class or includes a transitive dependency that does. You might need to exclude the javax.xml.namespace.QName class using a Maven dependency exclusion.
