我正在尝试使用Jenkins自动化我的Android应用程序构建，但是gradlew阶段始终会因该错误而失败
:app:compileDebugJavaWithJavacFatal Error: Unable to find package java.lang in classpath or bootclasspath
我正在手动下载并安装Android SDK和Java，因为Jenkins奴隶有时会被清除。
我的Jenkinsfile中用于构建apk的阶段如下：
stage('android sdk setup') {
steps {
sh 'wget https://download.java.net/java/jdk8u192/archive/b04/binaries/jdk-8u192-ea-bin-b04-linux-x64-01_aug_2018.tar.gz'
sh 'tar xvf jdk-8*.tar.gz'
script {
JAVA_HOME='jdk1.8.0_192'
}
sh 'wget https://dl.google.com/android/repository/sdk-tools-linux-4333796.zip'
sh 'unzip -o sdk-tools-linux-4333796.zip'
script {
sh 'mkdir sdkTools'
env.ANDROID_HOME = "sdkTools"
env.PATH = "tools:tools/bin:${env.PATH}"
}
// ensures that all platform licences are automatically accepted
sh 'yes | sdkmanager --licenses --sdk_root=sdkTools'
}
}
stage('build debug apk') {
steps {
sh './android/gradlew assembleDebug -p android/'
}
}
失败的gradlew阶段的日志（使用4.4级我们）：
Running shell script
+ ./android/gradlew assembleDebug -p android/

此外，当使用--info参数运行gradlew时，将输出与该步骤有关的以下内容：
：app：compileDebugJavaWithJavac-不是增量的（例如，输出已更改，之前没有执行等）。
