PlayN showcase（java）不运行 - 没有错误或警告

Question

我能够在昨天运行该示例，但尝试让playn与Eclipse一起工作后，它不再有效。它以HTML5的形式正常运行（mvn -Phtml集成测试）。

这里是我下载并运行playn样本/展示完整的输出：

Answer 1

使用-P开关指定平台。在你的情况（JAVA）说：

mvn test -Pjava

如果你想尝试HTML口，说：

mvn -Phtml integration-test

Answer 2

的playn网站是愚蠢的。

mvn test只是运行测试套件。相反，你应该运行mvn install，你会看到类似这样的：

... 
[INFO] Waiting for initial device list from the Android Debug Bridge 
[INFO] Found 1 devices connected with the Android Debug Bridge 
[INFO] android.device parameter not set, using all attached devices 
[INFO] Successfully uninstalled playn.showcase.android from <DEVICENAME> 
[INFO] Found 1 devices connected with the Android Debug Bridge 
[INFO] android.device parameter not set, using all attached devices 
[INFO] Successfully installed /home/wires/workdir/wordquiz-playn/playn-samples/showcase/android/target/playn-showcase-android-1.0-SNAPSHOT.apk to <DEVICENAME> 
... 

然后，您可以找到您的手机上的应用程序，它被称为“橱窗”，有一个圆形的绿色笑脸图片。

您也可以从命令行启动应用程序，只需cd android和mvn android:run。请注意，只有运行了之前安装的应用程序，它不会安装它。
