如何将svn命令输出分配给groovy脚本中的变量[重复]

Question

我有一个这样的groovy脚本-

def BRANCH_REV = sh script: "svn info \$url | grep 'Last Changed Rev' | awk '{ print \$4; }'", returnStdout: true , trim: true

println "ccsmp - downstream testing for: $BRANCH_REV"

假设此脚本获取最后的修订号，并将该值放入名为“BRANCH\u REV”的变量中，第二行将打印该值。但我不断得到null值，我的控制台输出如下-

[branches%2Ffeatures%2Fcre40_jenkins] Running shell script
+ svn info
+ grep 'Last Changed Rev'
+ awk '{ print $4; }'
23401               <-- It is printing the revision number here

[Pipeline] echo
ccsmp - downstream testing for: 0      <-- but when I try to print the $BRANCH_REV, it prints out 0

[Pipeline] sh
[branches%2Ffeatures%2Fcre40_jenkins] Running shell script
+ echo 0
0                                    <-- same thing happens when I try to echo $BRANCH_REV

如果您的脚本在Jenkinsfile中并且您的管道配置为签出该Jenkinsfile（IE Jenkinsfile与您的代码一起存储），您可以简单地执行以下操作：

def BRANCH_REV = "r${SVN_REVISION}"
echo "Revision is ${BRANCH_REV}"
