我有一个使用 gradle 构建系统的项目，我愿意向其中添加 New Relic 监控。
该项目（包括 New Relic）在 Linux (Fedora 20) 上运行良好，但无法在我的 Mac 开发系统上构建，并给出错误说明Agent JAR loaded but agent failed to initialize.
这是错误的完整日志：
Dev-1:test 0x4d$ ./gradlew clean

One of the two will be used. Which one is undefined.

我还使用新生成的基本项目进行了测试，但它失败并出现完全相同的错误。
如果重要的话，我使用 JDK 1.7u55 版本。
Thanks
不幸的是，u55 引入了一项更改，破坏了 New Relic 代理。目前，如果可能，请使用旧版本的 Java 在构建时解决此问题。这不应该影响生成的 APK。 New Relic 已意识到此问题并正在努力尽快修复。
