尝试运行playn给出的基本示例，想要使用该工具包。我正在按照此处的指示进行操作:http://code.google.com/p/playn/wiki/GettingStarted
但是，在执行克隆并从命令行运行mvn compile exec:java之后，它会给出以下响应:
mvn编译exec:java
[INFO] Scanning for projects...

现在完全迷路了。我看了给出的帮助页面，但是看来他们只是在跟我说另一种语言。作为Maven和playn的完整入门者，我到处都是。救命!
干杯:)
编辑:
经过拉动和以下指示之后，出现以下错误:

我也尝试在核心中，而是得到以下错误:

仍然有点失落。有任何想法吗？
最佳答案
我们刚刚更新了通过Maven调用Java后端的方式。您应该在PlayN Wiki上查看最新的“入门指南”。
但是，这也可以解决您的问题:
cd playn-samples
git pull
cd showcase
mvn test -Ptest-java
