Answer 1

有两个enviroment_variables指向不同are (java运行时环境)。Jenkins不知道他应该使用哪一个。

您可能已经在Jenkins中设置了enviroment_variable，在那里可以找到JRE。但同时，运行jenkins的OS也有一个enviroment_variable，它指向找到JRE的其他位置。

您可以自行决定要删除其中的哪一个。

Answer 2

试着这样构建你的项目，分两步：

./gradlew prepareDebugDependencies
./gradlew assembleDebug

有关原因的讨论，请参阅https://github.com/evant/gradle-retrolambda/issues/105。

另外(可能对其他人有帮助)，确保您已经设置了类似以下内容的环境变量：

export JAVA7_HOME=/usr/lib/jvm/java-7-oracle
export JAVA8_HOME=/usr/lib/jvm/java-8-oracle
export JAVA_HOME=$JAVA7_HOME
