Gradle 找不到文件/目录

Question

我正在尝试使用 Gradle 开始运行 jar 文件

我的任务如下所示:

task startServer(type: Exec) {
  workingDir file("${buildDir}/aux/server/server-S31-SNAPSHOT")
  commandLine 'java -client -d64 -Xms256M -Xmx512M -DisableExplicitGC -XX:MaxPermSize=128M -jar server-S31-SNAPSHOT.jar'
}

我的文件夹和文件实际上就在那里。

我能跑

cd 'path/to/file'
java -client -d64 -Xms256M -Xmx512M -DisableExplicitGC -XX:MaxPermSize=128M -jar server-S31-SNAPSHOT.jar

很好。

然而gradle返回的异常是找不到文件或目录:

我可能遗漏了什么？

在Gradle Build Language Reference中可以看出, Exec.commandLine 需要一个 Iterable 或参数数组。尝试将 .split(' ') 附加到您的字符串。
