WSO2工具（eclipse）错误未处理的事件循环异常：带有groovy脚本的脚本调解器

篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了WSO2工具（eclipse）错误未处理的事件循环异常：带有groovy脚本的脚本调解器相关的知识，希望对你有一定的参考价值。
运行WSO2 EI 6.1.1我想在eclipse中使用groovy添加一个脚本调解器，但每当我这样做时，Eclipse会出现Unhandled事件循环异常（如果我通过图编辑器添加）或** Save Failed - > org / codehaus / groovy / control / CompilerConfiguration **（如果我在源视图中添加）。
使用以下序列定义复制很容易：
<?xml version="1.0" encoding="UTF-8"?>
<sequence name="test" trace="disable" xmlns="http://ws.apache.org/ns/synapse">
<script language="groovy"><![CDATA[def version = GroovySystem.version
mc.setProperty("groovyVersion",version);]]></script>
</sequence>
请注意，如果我在ESB Web控制台中编辑序列并在其中添加介体和groovy代码，那么它可以正常工作 - 因此ESB配置文件上的Groovy运行时本身没有问题，但是它使得维护碳应用程序非常笨拙，因为我找不到任何方法将这些groovy脚本调解器打包到我的应用程序中，其余的。来自eclipse的包。因为eclipse只是拒绝保存它们！

更新WSO2工具包修复此问题，以便从以下软件站点添加
https://product-dist.wso2.com/p2/developer-studio-kernel/4.1.0/ei-tools/releases/1.1.0/。
我后来遇到了关于groovy版本的classpath中的冲突的问题，由于@daggett提供的提示，我能够解决这个问题
