在Jython中打开NetLogo模型时引发Java非法参数异常

我试图使用运行在OSX El Capitan（10.11.6）上的Jython 2.7.0（在Java1.8.0131上）来控制NetLogo的API来运行实验。在尝试运行以下代码时：

import site
site.addsitedir("/Users/nqe/NetLogo/NetLogo 6.0.1/Java/")
import org.nlogo.headless.HeadlessWorkspace as hw

workspace = hw.newInstance()
workspace.open("models/Sample Models/Earth Science/Fire.nlogo")
workspace.command("set density 62")
workspace.command("random-seed 0")
workspace.command("setup")
workspace.command("repeat 50 [ go ]")
print (workspace.report("burned-trees"))

workspace.dispose()

我得到以下错误：

如果“导入站点”部分不清楚，我会执行以下操作：

创建jython脚本，将“/Users/nqe/NetLogo/NetLogo 6.0.1/Java/”中的所有.jar文件写入.pth文件

然后我将这个.pith文件与.jar文件一起放在…/Java/目录中

这允许我在需要导入NetLogo的各种API功能时从sys.path访问所有.jar依赖项 我无法准确地找出导致此错误的原因，因为在python交互模式下运行时，我能够使用hw.newInstance（）命令成功地创建NetLogo JVM的新实例（在运行此代码时，我可以看到弹出一个Java图标），例如，如果我没有指定url，open命令就会抛出相应的错误

因此，我认为这可能与我的JVM配置不正确有关，所以我尝试了一些方法

首先，我检查了我是否能够实际运行在headless模式下控制NetLogo API的java示例，在这里可以找到：。我能够使用以下命令运行此处给出的代码：

javadir=/Users/nqe/NetLogo/ControlAPI/
netjardir=/Users/nqe/NetLogo/NetLogo\ 6.0.1/Java/netlogo-mac-app.jar

javaname=Example1

javac -cp "${javadir}":"${netjardir}" $javaname.java
java -cp "${javadir}":"${netjardir}" $javaname 

无需手动更改任何JVM设置。尽管如此，在运行jython代码时，我还是继续尝试更改JVM设置，例如文档和扩展的路径，尤其是./lib目录的路径。不幸的是，指定以下JVM设置：

-Djava.library.path=~/JRE/Contents/Home/jre/lib/

对事业毫无帮助。请注意，~ here是NetLogo 6.0.1目录中的缩写，这是我能找到的唯一lib目录

最后，我不同意这一点：当我试图运行上面的jython脚本时，仅指定netlogo-mac-app.jar的路径，我无法导入headless类内容。因此，在只指定这一个.jar类路径的情况下编译/运行java可能会以某种方式访问NetLogo工作所需的一些有用的元数据（我不知道在我的java背景水平下这是否可行）

考虑到这一点，我在~/NetLogo 6.0.1.app/Contents/Java/中找到了一个NetLogo.cfg文件，其中包含以下信息：

这看起来很有希望，但是通过打开应用程序/使用Control API with Java方法，删除这个文件并不会影响我运行NetLogo的能力。正因为如此，我被难倒了，所以任何帮助都将不胜感激

NetLogo要求JVM启动时的当前工作目录是NetLogo目录。@SethTisue不幸的是，这样做不行，但我最终决定只从Java控制API，在Java中我可以更明确地控制JVM设置。然而，在这样做的过程中，我遇到了第二个小问题，这个问题可能不能保证整个帖子的正确性：当直接使用NetLogo API控制API时，NetLogo能否像在BehaviorSpace中那样在多个线程中运行，或者我现在必须作为用户显式地用Java控制线程吗？这是一个好问题-请就此提出一个新问题。@Nic您需要自己用Java控制线程
