XmlSerializer throws java.lang.reflect.InvocationTargetException

Hi there,

I'm trying to serialize a settings class with xml serializer and get the following error: java.lang.reflect.InvocationTargetException


Here is my settings implementation:

@State(
        name = "Typo3StormSettings",    // must be equal to the class name I think
        storages = {
                // @Storage(id = "default", file = StoragePathMacros.PROJECT_FILE),
                // @Storage(id = "default", file = "/tmp/test/"),
                // @Storage(id = "dir", file = StoragePathMacros.PROJECT_CONFIG_DIR + "/typo3storm.xml", scheme = StorageScheme.DIRECTORY_BASED)
                @Storage(id = "dir", file = "/tmp/test/typo3storm.xml", scheme = StorageScheme.DIRECTORY_BASED)
        }
)
public class Typo3StormSettings implements PersistentStateComponent<Typo3StormSettings> {

    // Those fields should be serialized
    public boolean enabled = true;
    public String pathToTypo3;



    @Transient // Do not serialize this field!
    protected Project project;



    public static Typo3StormSettings getInstance(Project project) {
        Typo3StormSettings settings = ServiceManager.getService(project, Typo3StormSettings.class);

        if(settings == null){
            IdeHelper.logError("Cannot find Typo3Storm Settings");
        }

        settings.project = project;

        return settings;
    }



    @Override
    public Typo3StormSettings getState() {
        return this;
    }



    @Override
    public void loadState(Typo3StormSettings typo3StormSettings) {
        try{
            XmlSerializerUtil.copyBean(typo3StormSettings, this);
        }
        catch(Exception e){
            // IdeHelper.logError(e.getMessage());
            // IdeHelper.showDialog(null,"Cannot read the saved settings for Magicento. Please try saving them again from File > Settings > Magicento", "Error in Magicento Settings");
        }
        // autoSetPathToMage();
    }



    public boolean isEnabled() {
        return enabled;
    }



    public String getPathToTypo3() {
        return getPathToTypo3();
    }



    public void setPathToTypo3(String pathToTypo3) {
        this.pathToTypo3 = pathToTypo3;
    }

}

And here is a simple testcase, I set up to reproduce the error:

public class Typo3StormSettingsTests {

    @Test
    public void settingsCanBeSerialized() {
        Typo3StormSettings settings = new Typo3StormSettings();
        settings.setPathToTypo3("/tmp");
        XmlSerializer.serialize(settings);
    }

}

I'm getting the same error, if I run the plugin from within PHPStorm Application, if I uncomment the annotations and use the following @State annotation:

 */
@State(
        name = "Typo3StormSettings",    // must be equal to the class name I think
        storages = {
                @Storage(id = "default", file = StoragePathMacros.PROJECT_FILE),
                @Storage(id = "dir", file = StoragePathMacros.PROJECT_CONFIG_DIR + "/typo3storm.xml", scheme = StorageScheme.DIRECTORY_BASED)
        }
)

It would be really great if you could help me out on that issue!

Best regards,

Mimi
