Jenkins sbt-launch.jar失败-无法加载主类

我有一个jenkins构建来检查sbt，它失败了，错误如下：

[sbt-check] $ /var/hudson/tools/java1.8.0_51/bin/java /var/hudson/tools/sbt-0.13.12/bin/sbt-launch.jar -Dsbt.log.noformat=true -jar  clean assembly

sbt包安装在服务器上。我从下载了软件包SBT-0.13.12.TGZ，并创建了它的RPM以将其安装到我的服务器上。软件包已安装，我已在manage jenkins中配置了sbt启动路径

我也遇到了同样的问题。你爸爸喜欢吗？
