Import Java Maven project into Eclipse workspace for Android
A Maven project may or may not work depending on whether its dependency is supported by Android.
For errors related to plugins such as "null (org.jvnet.jaxb2.maven2:maven-jaxb2-plugin:0.8.3:generate:default:generate-sources)", including <plugins> in <pluginManagement>.
For error "GroupId is duplicate of parent groupId", just change the id.
