Question

I am adding some functionality to an existing application to show debug info. When examining an error from the error log view it shows something called “session data”, typically it looks like:

eclipse.buildId=M20090917-0800
java.version=1.6.0_11
java.vendor=Sun Microsystems Inc.
BootLoader constants: OS=win32, ARCH=x86, WS=win32, NL=sv_SE
Framework arguments:  -product org.eclipse.epp.package.rcp.product
Command-line arguments:  -os win32 -ws win32 -arch x86 -product org.eclipse.epp.package.rcp.product

This is something that could be useful to know. how can I get this information?

Answer 1

Some of those information should be able from a Plugin through the org.eclipse.core.runtime.Platform class, as shown by the org.eclipse.debug.internal.core.SystemVariableResolver source code:

public String resolveValue(IDynamicVariable variable, String argument) throws CoreException {
    if ("ARCH".equals(argument)) { //$NON-NLS-1$ 
        return Platform.getOSArch(); 
    } else if ("ECLIPSE_HOME".equals(argument)) { //$NON-NLS-1$ 
        URL installURL = Platform.getInstallLocation().getURL(); 
        IPath ppath = new Path(installURL.getFile()).removeTrailingSeparator(); 
        return getCorrectPath(ppath.toOSString()); 
    } else if ("NL".equals(argument)) { //$NON-NLS-1$ 
        return Platform.getNL(); 
    } else if ("OS".equals(argument)) { //$NON-NLS-1$ 
        return Platform.getOS(); 
    } else if ("WS".equals(argument)) { //$NON-NLS-1$ 
        return Platform.getWS(); 
    } 
    return null;
} 

Platform.getCommandLineArgs() should complete the display for the eclipse session (not for your program though).

For a RCP program, see this thread

Using the Application start(IApplicationContext context) method:

String[] args = (String[]) context.getArguments().get(IApplicationContext.APPLICATION_ARGS);
