Jenkins使用SBT构建错误-java.io.IOException:无法运行程序；javac"；错误=2，没有这样的文件或目录

我正在为我的Scala项目设置Jenkins。我正在使用sbt来构建项目。在构建时，我遇到了这个错误

我还在Jenkins全局工具配置部分设置了JVM路径

请帮我确定我可能做错了什么。如果你们需要更多的信息，请告诉我

仅供参考-路径确实存在

echo $JAVA_HOME
/usr/lib/jvm/java-8-openjdk-amd64/jre

echo $PATH
/usr/lib/jvm/java-8-openjdk-amd64/jre/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin
