[修复了问题]我把一个jar文件放在特别目录下.我删除了它,我可以使用Android Studio启动应用程序.

[问题]我使用Mac OS X.在出现Android Studio之前,我安装了groovy,gradle with gvm.我使用了android gradle插件.

我从Android开发人员安装Android Studio并尝试构建应用程序.但,

...

:HelloAndroidStudio:packageDebug FAILED

FAILURE: Build failed with an exception.

出了什么问题:任务执行失败':HelloAndroidStudio:packageDebug'.

class org.bouncycastle.asn1.ASN1Primitive重写final方法equals.(Ljava/lang/Object;)Z

尝试:使用--stacktrace选项运行以获取堆栈跟踪.使用--info或--debug选项运行以获取更多日志输出.

我的设置有误？

需要Additinal System变量(JAVA_HOME)设置吗？

请帮我.

我接下来添加了Exception.

例外情况是:

就像C#LINQ Enumerable一样#First with delegate方法和Scala List #ref方法,在Java8中,是否有一种方法可以找到列表中第一个匹配的元素？

我正在寻找有关Kotlin中访问修饰符的文档.但它没有根据.

我想知道并检查Kotlin和Java中的包函数和差异保护修饰符的访问修饰符.

[编辑]我正在寻找Jetbrians的公共文件.

我找到了关于访问修饰符的线程. http://devnet.jetbrains.com/thread/451236?tstart=0
