java - 尝试从 bash 运行BehaviorSpace 实验时出错

Question

我正在 NetLogo 中运行我的模型，它运行良好。当我尝试运行一些在 xml 文件中定义并使用此脚本启动的实验时，发生了奇怪的事情:

java -Xmx4096m -Dfile.encoding=UTF-8 -cp /Applications/NetLogo\ 5.3/Java/netlogo-mac-app.jar org.nlogo.headless.Main --model mymodel.nlogo --setup-file experiments-.25-times-per-day.xml

我不明白从错误消息中查看哪里，因为它没有指向模型的任何特定部分 - 据我所知......

这是我的设置文件的摘录:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE experiments SYSTEM "behaviorspace.dtd">
<experiments>
 <experiment name="india-hagerstrand-one-at-random" repetitions="100" runMetricsEveryStep="false">
    <setup>setup</setup>
    <go>go</go>
    <enumeratedValueSet variable="dataset">

    </enumeratedValueSet>
    <enumeratedValueSet variable="schedule">
        <value value="&quot;one at random&quot;"/>
    </enumeratedValueSet>
    <enumeratedValueSet variable="logic">

    <enumeratedValueSet variable="debug?">

    </enumeratedValueSet>
    <enumeratedValueSet variable="ticks-in-semester">

    </enumeratedValueSet>
    <enumeratedValueSet variable="experiment">
        <value value="experiment-.25"/>
    </enumeratedValueSet>
</experiment>
</experiments>

只有当我从 xml 文件加载实验时才会发生错误，否则它会起作用。我已根据 Behaviourspace.dtd 验证了我的 xml，它似乎是正确的。

该错误是由xml代码引起的，具体来说，封装字符串时有一行错误:

<enumeratedValueSet variable="experiment">
    <value value="&quot;experiments-4&quot;"/>
</enumeratedValueSet>
