我编写了一个Gradle任务，通过命令行执行fastlane supply命令。该任务如下：
task uploadToPlayStore(type: Exec) {
group = "upload"
commandLine "fastlane", "supply",
"--aab", "$project.rootDir/app/build/outputs/bundle/upload/${archiveFile}.aab",
"--mapping", "$project.rootDir/app/build/outputs/mapping/upload/mapping.txt",
"--skip_upload_apk", "true",
"--skip_upload_metadata", "true",
"--skip_upload_images", "true",
"--skip_upload_screenshots", "true",
"--track", "internal",
"--package_name", "$appPackage",
"--json_key", "~/Documents/key.json"
}
这个任务在我所在的Jenkins从机终端上以及通过Android Studio作为Gradle任务和通过./gradlew uploadToPlayStore命令在终端上成功运行。在最开始，通过Android Studio的终端运行不正常，直到我通过使Android Studio的缓存失效并重启后才解决了问题。它一直报错：
org.gradle.api.tasks.TaskExecutionException: Execution failed for task ':app:uploadToPlayStore'.
...............
Caused by: org.gradle.process.internal.ExecException: A problem occurred starting process 'command 'fastlane''
...............
Caused by: net.rubygrapefruit.platform.NativeException: Could not start 'fastlane'
...............
Caused by: java.io.IOException: Cannot run program "fastlane" (in directory "/Users/..."): error=2, No such file or directory
...............
Caused by: java.io.IOException: error=2, No such file or directory
目前，当我尝试运行我的Jenkins多分支流水线时，我遇到了之前在Android Studio中遇到的相同错误。从目前为止我所发现的情况来看，似乎Jenkins无法找到
fastlane命令。我尝试为构建项目的节点设置环境变量，但仍然遇到相同的错误。这是我在
Jenkinsfile中运行Fastlane任务的stage：stage('Upload To Google Play Store') {
steps {
script {
if (env.BRANCH_NAME.startsWith("release")) {
sh './gradlew uploadToPlayStore --stacktrace'
} else {
echo 'Skipping stage since we\'re not on a release branch...'
}
}
}
}
更新（1）：当以"~/.rvm/rubies/ruby-2.4.2/bin/fastlane","supply",...命令运行时，启用--debug标志，我会得到以下堆栈跟踪：

更新（2）：经过大约一天的调试，我发现当我通过Jenkins节点的Script Console运行gem env命令时，我得到了不同的RUBYGEMS版本、gem路径和shell路径。我正在尝试让Jenkins节点使用安装在机器上的Ruby Gems而不是它自己的（或类似的东西）。
更新（3）：经过大约3天的调试，我终于成功找出了问题所在。问题在于，在运行Jenkins流水线作业时，您无法通过标准Web界面和插件（如EnvInject）设置环境变量。此外，Mac OS有一个内置的ruby环境，默认情况下由Jenkins节点使用，但我无法在其中安装Fastlane Gem。
