我想在该插件中启动Jython解释器,然后在解释器内执行文件。尝试安装Jython解释器时发生错误
package com.jakob.jython;
import org.bukkit.plugin.java.JavaPlugin;
import org.python.core.PyObject;
import org.python.util.PythonInterpreter;
import java.io.IOException;
import java.io.InputStream;
import java.util.logging.Logger;
public class EmbeddedJython extends JavaPlugin {
private static final Logger log = Logger.getLogger("Minecraft");
private PythonInterpreter interpreter;
private PyObject plugin;
public void onEnable() {
log.info("JythonTest enabled");
this.interpreter = new PythonInterpreter();
log.info("Jython interpreter fired up and cooking on gas");
log.info("Loading Python Plugin");
InputStream pythonScript = EmbeddedJython.class.getResourceAsStream("MyPlugin.py");
this.interpreter.execfile(pythonScript, "MyPlugin.py");
log.info("Getting plg method.");
this.plugin = this.interpreter.get("plg");
log.info("Plugin loaded");
log.info(plugin.invoke("onEnable").toString());
}
public void onDisable() {
log.info(plugin.invoke("onDisable").toString());
log.info("Jython disabled");
}
}
在我能得到Jython解释和运行字符串我的手,但是当我用上面的代码我结束了,看起来像这样的异常等检查:

莫非它是我使用execfile
错误? 或者这是一个错误或我错过了InputStream
如何工作?
hmm如果我创建一个文件对象,如'私人文件pythonFile =新文件('MyScirpt.py');'然后手'getResourceAsStream(pythonFile.getAbsolutePath());'? –
