Dear all,
I used eclipse PDE + m2eclipse to develop spring osgi bundle. My steps
are:
1. Create a project throght m2eclpse wizard, I selected the archettype
is spring-osgi-bundle-archetype;
2. Add the dependencies in POM.xml file, m2eclipse downloaded the jar
files and added them into Maven library list in eclipse.
3. Create a directory named "osgi runtime" to use it as a target
platform by eclipse, and configurated in eclipse through menu
"Preference"-"Plugin-development";
3. Run mvn eclipse:install-plugins to copy all dependencies from maven
repository into the target platform mentioned above.
However, the error occured, it showed:
Exception in thread "main" java.lang.NullPointerException
