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)        }
)publicclass Typo3StormSettings implements PersistentStateComponent<Typo3StormSettings> {     // Those fields should be serialized    publicboolean enabled = true;    public String pathToTypo3;       @Transient // Do not serialize this field!    protected Project project;       publicstatic 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() {        returnthis;    }       @Override    publicvoid 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();    }       publicboolean isEnabled() {        return enabled;    }       public String getPathToTypo3() {        return getPathToTypo3();    }       publicvoid setPathToTypo3(String pathToTypo3) {        this.pathToTypo3 = pathToTypo3;    } }

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

publicclass Typo3StormSettingsTests {     @Test    publicvoid 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
