Question

我使用Mule 3.3.0和JDK7构建了一个自定义云连接器，一切正常。当更新到Mule 3.4.0时，我遇到了传递@Processor函数List参数的问题。

@Processor
public String myProcessor(String content)
{
    return content;
}

这个编译很好，但是这个

@Processor
public String myProcessor(List<String> content)
{
    return "content";
}

引发以下错误：

[ERROR] Failed to execute goal org.mule.tools.devkit:mule-devkit-maven-plugin:3.4.0:generate-sources (default-generate-sources) on project enterprise-message-adapter: java.lang.InstantiationError: com.sun.tools.javac.util.Name$Table -> [Help 1]

如果我将我的JAVA_HOME更改为1.6，这可以正常工作。我尝试过使用maven-compiler-plugin，但无济于事。

Answer 1

这是DevKit的众所周知的限制：现在你必须使用JDK6来编译你的项目。

我不确定您是否可以查看JIRA：http://www.mulesoft.org/jira/browse/DEVKIT-261但如果是，请向上投票！

Answer 2

我能够使用不同的Mule组件版本（包括devkit 3.4.3）在OS X上使用它。这可能会导致其他人的问题，但我能够使用Mule 3.4.0 CE运行时和JDK™7成功创建，打包和部署Anypoint连接器，并使用下面列出的pom声明。

这适用于当前版本的Anypoint Studio和Maven。
