debug maven app locally does not work with the java debug extension

Comienza con la workspace launch.config para mainClass at.mytoolx.batch.mytoolAppLoader y compara las líneas de comandos de Java de Eclipse y VS Code que se muestran en el informe. Reproduce el lanzamiento de depuración local con el argumento VOR_BGZ50 proporcionado y, después, inspecciona cómo la Java debug extension construye el classpath y las opciones de depuración. Se considera terminado cuando la aplicación alcanza "Hello World" en VS Code sin la excepción de inicialización indicada.

Hi, we have a maven app, which is deployed to the mainframe, and we building our own application to fit Java Maven apps into our vscode workflow.

So we need to debug java maven apps for quarkus (maybe open liberty) and for mainframe batch.

To Debug the app local i used this minimal snippet which is working fine in eclipse...

@Dependent
public class BGZ50FileCreator extends JhapBatchApp {

    private final static String appName = "VOR_BGZ50";
    @Override
    public String getAppName() {
        return appName;
    }

    @Override
    public void run() throws CheckedBusinessException {
        System.out.println("Hello World");
    }   
}

In Vscode this exception is thrown before "Hello World" is printed

Unable to invoke public void  at.mysecretlib.init()  
...
Caused by: java.lang.reflect.InvocationTargetException
...
Caused by: java.lang.NullPointerException

When comparing eclipse and vscode command for debug:

eclipse:

C:\mypath\jdk\1.8.0.262-3.b10.redhat.windows.x86_64\bin\javaw.exe -agentlib:jdwp=transport=dt_socket,suspend=y,address=localhost:62642 "-javaagent:C:\mypath2\configuration\org.eclipse.osgi\424\0.cp\lib\javaagent-shaded.jar" -Dfile.encoding=UTF-8 -classpath
"C:\mymaven\at\mytool\mytool-batch\2.171.6\mytool-batch-2.171.6.jar;
....
at.mytoolx.batch.mytoolAppLoader VOR_BGZ50

vscode:

c:\mypath\jdk\1.8.0.262-3.b10.redhat.windows.x86_64\bin\javaw.exe' '-agentlib:jdwp=transport=dt_socket,server=n,suspend=y,address=localhost:50209' '-cp' 'C:\myrepo\myproject\target\classes; C:\mymave\at\mytool\mytool-batch\2.171.6\mytool-batch-2.171.6.jar;
...
'at.mytoolx.batch.mytoolAppLoader' 'VOR_BGZ50'

The noteable differences are the missing javaagent, the additional "server=n" and an additional entry as first argument in classpath.

launch.config (in workspace file)

    "configurations": [
      {
        "type": "java",
        "name": "Java",
        "request": "launch",
        "mainClass": "at.mytoolx.batch.mytoolAppLoader",
        "projectName": "myproject",
        "args": "VOR_BGZ50",
        "javaExec": "c:\\mypath\\jdk\\1.8.0.262-3.b10.redhat.windows.x86_64\\bin\\javaw.exe",
        "shortenCommandLine": "none",
      }

Thanks!
