RE: [m2] plugin classpath question

[Van Steenberghe Mario (GFDI)]

Thanks. 

In fact my plugin calls a library that loads some resources inside these 
libraries, so I had to switch the context classloader as follows:

public void executeReport(final Locale locale) throws MavenReportException {
  final Thread current = Thread.currentThread();
  final ClassLoader oldLoader = current.getContextClassLoader();
        
  try {
    current.setContextClassLoader(BeanDocClient.class.getClassLoader());
  
    // ... call library code here ...
  }
  catch (Exception e) {
    throw new MavenReportException("Unable to generate beandoc: " + 
e.getMessage(), e);
  }
  finally {
    current.setContextClassLoader(oldLoader);
  }
}

Regards,
Mario.

The plugin gets the plugin's dependencies, not the project's.

Also, it uses a separate class loader, so the system classpath only
reflects what was used to bootstrap Maven (classworlds).

You can get the JARs for the project's artifacts using the
${project.artifacts} expression.
