以防万一其他人尝试在自构建的 eclipse 插件中使用 Jython。当我尝试通过 interpreter.exec("from myScript import *\n"); 导入我的 python 脚本时，我遭受了 2 天的以下错误：

!ENTRY org.eclipse.ui 4 0 2015-12-11 11:22:53.549

【解决方案1】：

需要将属性python.home 设置为某个值。看起来哪个值都无关紧要..将其留空是不行的。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", ".");
