我有一个jenkins构建来检查sbt，它失败并出现以下错误：
[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
Error: Could not find or load main class .var.hudson.tools.sbt-0.13.12.bin.sbt-launch.jar

sbt软件包安装在服务器上。我从http://www.scala-sbt.org/download.html下载了包SBT-0.13.12.TGZ并创建了它的RPM以将其安装在我的服务器上。已安装包，我已在manage-jenkins中配置了sbt-launch的路径。
