jenkins pipeline通过chage-id获取远程change分支名导致shell命令一直失败_jenkins pipline changes

出现的问题：

出现问题的代码如下： 

def cherry_pick() {
    String cherryPickCommitId = CHERRY_PICK_COMMITID
    String cherryPickBranch = CHERRY_PICK_BRANCH
    echo "cherryPickBranch = ${cherryPickBranch}"
    echo "cherryPickCommitId = ${cherryPickCommitId}"
    String[] str;
    str = cherryPickCommitId.split(' ');
    echo "cherryPickCommitId : "
    
    for( String values : str ) {
        println(values)
        
        int patch_sets_number = sh(  returnStdout: true, script: "ssh -p 29418 user@git.***.com  gerrit query --format=JSON --patch-sets change:${values} | sed -n '1p' | jq '.patchSets' | grep number | wc -l")
        echo "patch_sets_number=${patch_sets_number}"
        int patch_sets_latest = patch_sets_number - 1
        echo "patch_sets_latest=${patch_sets_latest}"
        def refs_change = sh(  returnStdout: true, script: "ssh -p 29418 user@git.***.com  gerrit query --format=JSON --patch-sets change:${values} | sed -n '1p' | jq '.patchSets[$patch_sets_latest].ref' | sed 's/\"//g'")
        echo "patch_sets_latest = ${patch_sets_latest} refs_change = ${refs_change}"    
        sh "git fetch idb ${refs_change}:${values}"
    }   
}

解决：将获取jsonl里的分支名后删除换行符就可以了 

def refs_change = sh(  returnStdout: true, script: "ssh -p 29418 aiot-robot@git.xiaomi.com  gerrit query --format=JSON --patch-sets change:${values} | sed -n '1p' | jq '.patchSets[$patch_sets_latest].ref' | xargs echo -n | sed 's/\"//g'")

删除换行符的操作，最简单的是：

echo  "55555" | xargs echo -n
