与maven集成玩框架

-1

我试图将玩框架（Java版本）与maven和intellij想法集成。为此我使用play2-maven-plugin（https://code.google.com/p/play2-maven-plugin/）;与maven集成玩框架

我创建了pom文件，如手册中所述。现在POM文件看起来像这样：

<project xmlns="http://maven.apache.org/POM/4.0.0"

在IntelliJ IDEA的，Maven的项目选项卡我点击插件=> play2 => paly2：运行

然后给出一个错误：

如果我尝试使用激活器运行项目，那么运行正常。我该怎么办才能解决这个问题，并使用maven运行项目，而不使用SBT？

该play2:run目标有一个executedProject参数是可选的。在没有使用过play2的情况下，我的第一个猜测是，它不是目标所假设的目标。如果您运行mvn ... -e -X（打印错误和调试信息），您是否看到了它实际设置的值？

第一个问题（用play2） - 在1.0.0-alpha9中，错误信息得到了改进，现在它告诉我们在这种情况下该怎么做。这是问题https://code.google.com/p/play2-maven-plugin/issues/detail?id=29的一部分，请参阅最后的评论。

第二个问题（使用sbt编译器）在1.0.0-beta5中修复 - 请参阅问题https://code.google.com/p/sbt-compiler-maven-plugin/issues/detail?id=14。
