Eclipse插件+ Jython-未处理的事件循环异常

Question

以防万一有人尝试在自建的eclipse插件中使用Jython。 我在以下错误上遭受了2天的错误，该错误是在我尝试通过interpreter.exec("from myScript import *\\n");导入python脚本时发生的interpreter.exec("from myScript import *\\n"); ：

需要将属性python.home设置为某个值。 看起来哪一个值都没有关系..不能将其留空。 设置属性例如可以在java代码中完成：

    String jythonJarPath = "target/lib/jython-standalone-2.7.0.jar";
    String pythonLibPath = SilecsUtils.findInBundle(jythonJarPath);
    Properties sysProps = System.getProperties();
    sysProps.setProperty("python.path", pythonLibPath + "/Lib");
    sysProps.setProperty("python.home", ".");
