I built a custom cloud connector with Mule 3.3.0 and JDK7, and everything was working fine. When updating to Mule 3.4.0 I ran into an issue with passing @Processor functions List parameters. 

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

This compiles fine, but this

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

throws the following error: 

[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]

If I change my JAVA_HOME to point at 1.6 this works fine. I've tried using the maven-compiler-plugin, but to no avail.

这是 DevKit 的一个众所周知的限制：现在您必须使用 JDK6 来编译您的项目。

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

我能够使用不同 Mule 组件版本（包括 devkit 3.4.3）的混搭使其在 OS X 上运行。这可能会给其他人带来问题，但我能够使用 Mule 3.4.0 CE 运行时和 JDK™ 7 以及下面列出的 pom 声明成功地创建、打包和部署 Anypoint 连接器。

这适用于当前版本的 Anypoint Studio 和 Maven。
