这是一个典型的场景，有一天你醒来并意识到以前工作的东西因为未知原因而停止工作。＆＃34;
我有一个运行Gradle命令的Jenkins作业。现在，在成功构建之后，以下内容将抛出异常。
To honour the JVM settings for this build a new JVM will be forked. Please consider using the daemon: http://gradle.org/docs/2.2.1/userguide/gradle_daemon.html.
FAILURE: Build failed with an exception.
* What went wrong:
Unable to start the daemon process.
This problem might be caused by incorrect configuration of the daemon.
For example, an unrecognized jvm option is used.
Please refer to the user guide chapter on the daemon at http://gradle.org/docs/2.2.1/userguide/gradle_daemon.html
Please read the following process output to find out more:

答案 0 :(得分：1)
从您提供的描述和堆栈跟踪中，gradle尝试从作业配置中启动守护程序，而不是在结束时关闭它。这意味着下次尝试运行作业时，它无法启动守护程序，因为守护程序已在运行（因此构建失败）
考虑将守护程序从作业配置中取出并作为单独的进程运行（请参阅https://gradle.org/docs/current/userguide/gradle_daemon.html）
或者，要么添加条件检查以启动守护程序，只要它尚未运行或在构建结束时关闭守护程序（不推荐）
