gradle编译成功，但无法运行项目

问题

在我试图找出问题的根本原因之后。为什么我可以成功构建但无法运行项目。这是因为一个jar文件调用＆＃39; signalr-client-sdk.jar＆＃39;如果我放入libs文件夹并运行以下生成的错误消息。请帮我识别一下。我现在不知道该怎么做。

文件JAR DOWNLOAD

环境

  1. IntelliJ Idea 14.1.5
  2. Java JDK 1.7.0_79
  3. gardle wrapper - gradle-2.2.1-all.zip

2 个答案:

答案 0 :(得分：2)

您的真正错误是

Caused by: com.android.dx.cf.iface.ParseException: bad class file magic (cafebabe) or version (0034.0000)

这是因为您的signalr-client-sdk.jar是使用Java 1.8编译的：

javap -verbose -classpath signalr-client-sdk.jar microsoft.aspnet.signalr.client.transport.HttpClientTransport | grep version

  minor version: 0
  major version: 52

52是Java 1.8。

您应该使用Java 1.7重建SignalR客户端（javap应该返回major version: 51）。

答案 1 :(得分：0)

下载最新版本的gradle

或者您可以使用

 classpath 'com.android.tools.build:gradle:1.2.3'

然后重建和文件 - ＆gt;使缓存无效/重新启动
