Eclipse插件新编辑器无法断点

我使用Eclipse插件创建了一个新的编辑器。但是不会创建任何断点。我认为是CompilationUnitEditor的问题，所以请回答解决方案。

@Override protected void createPages() { try { // Sets file name as title this.setPartName(getEditorInput().getName());

    // service editor
    editor = new CompilationUnitEditor();
    addPage(Page.SERVICE_SOURCE.ordinal(), editor, getEditorInput());
    setPageText(Page.SERVICE_SOURCE.ordinal(), EditConst.TITLE_SERVICE_EDITOR_TAB1);

    // initializes
    iCompilationUnit = JavaUI.getWorkingCopyManager().getWorkingCopy(getEditorInput());

    // service viewer
    viewer = new ServiceViewer(getContainer(), this, iCompilationUnit);
    addPage(Page.SERVICE_VIEWER.ordinal(), viewer);
    setPageText(Page.SERVICE_VIEWER.ordinal(), EditConst.TITLE_SERVICE_EDITOR_TAB2);

    // service PMD
    inspection = new ServiceInspection(getContainer(), this, iCompilationUnit);
    addPage(Page.SERVICE_INSPECTION.ordinal(), inspection);
    setPageText(Page.SERVICE_INSPECTION.ordinal(), EditConst.TITLE_SERVICE_EDITOR_TAB3);

    // add event listener
    addPageChangedListener(this);

}catch(Exception e) {
    e.printStackTrace(System.err);
    throw new RuntimeException(e);
}

}
