Android Maven build gives trouble processing “javax/xml/namespace/QName.class”:

Question

Following error is showing in Maven console everytime I do Project -> Clean. Only the jar file is built in the target folder, apk

Answer 1

You can exclude implicit dependencies using the exclude-tag. QName seems to be in e.g. the xpp3 package. I solved this problem by adding the following exclusions to my pom (that already contained the dependency to google-api-client-googleapis):

<dependency>
  <groupId>com.google.api.client</groupId>
  <artifactId>google-api-client-googleapis</artifactId>
  <version>1.4.1-beta</version>
  <exclusions>
    <exclusion>
      <groupId>commons-logging</groupId>
      <artifactId>commons-logging</artifactId>
    </exclusion>
    <exclusion>
      <groupId>xpp3</groupId>
      <artifactId>xpp3</artifactId>
    </exclusion>
</exclusions>
</dependency>

If you need to find where the conflicting class files come from, run for example:

for x in `find ~/.m2/repository/ -name \*.jar`; do jar tf $x|grep QName.class && echo "Found in: $x"; done`

If your are using android maven integration, you should add the "provided" scope in your android sdk dependency.

<dependency>        
<groupId>com.google.android</groupId>        
<artifactId>android</artifactId>        
<version>2.3.3</version>        
<scope>provided</scope>        
</dependency>
