NumberFormatException on eclipse start

I'm a novice at Java and eclipse IDE. I'm trying to create a plugin to my installed eclipse 4.4.0 by the official IBM article. I've added plug-in description to the plugin.xml:

<extension point="org.eclipse.debug.core.launchConfigurationTypes">
    <launchConfigurationType
        name="MyConfiguration"
        delegate="com.myplugin.first.launching.MyLaunchConfiguration"
        modes="run, debug"               
        id="com.myplugin.first.launching.myConfiguration">        
    </launchConfigurationType>
</extension>

and I've created empty configuration delegate with required dependencies. Unfortunately I cannot launch a new eclipse application with my plugin because every time I get the following error:

    An error has occurred. See the log file
    null.

I have not found the log file with the error. What's wrong? What should I do?

Maybe somebody knows the problem.

Solution

  • Well! I,ve fixed the problem. I just created a new workspace and copied my project and config files to the workspace.

    So the problem was in a broken workspace. I guess some workspace config file was corrupted. Anyway thank redoc for the idea.
