想要并行觸發幾個下游作業是使用 groovy 的宣告式管道。嘗試如下，但遇到了問題。它正在檢查條件，但似乎在并行塊上遇到問題。
stage("CHeck for downstraem jobs"){
agent {
node {
label "${AGENT}"
customWorkspace "${SRC}"
}
}
environment {
UPSTREAM_PARAMS = "${SRC},${AGV}"
ADM_FILES = sh (script: 'cd ${SRC}/repo; git diff-tree --no-commit-id --name-only -r $(git log --format="%H" -n 1) | grep "src/util"',
returnStatus: true
)
FUNC_FILES = sh (script: 'cd ${SRC}/repo; git diff-tree --no-commit-id --name-only -r $(git log --format="%H" -n 1) | grep "include"',
returnStatus: true
)
CONT_FILES = sh (script: 'cd ${SRC}/repo; git diff-tree --no-commit-id --name-only -r $(git log --format="%H" -n 1) | grep "src/test"',
returnStatus: true
)
TOOL_FILES = sh (script: 'cd ${SRC}/repo; git diff-tree --no-commit-id --name-only -r $(git log --format="%H" -n 1) | grep "tools"',
returnStatus: true
)
}
steps{
echo "Build dir is ${SRC}"
echo "CHANGED FILES ARE ${ADMIN_FILES}"
echo "CHANGED FILES ARE ${FUNC_FILES}"
echo "CHANGED FILES ARE ${CONT_FILES}"
echo "CHANGED FILES ARE ${TOOL_FILES}"
script {
if (ADM_FILES == '0' && FUNC_FILES == '0' && CONT_FILES == '0') {
echo "trigger parallel both jobs"
parallel {
stage('Launch JOB admin'){
agent any
environment {
UPSTREAM_PARAMS = "${SRC},${AGV}"
}
steps {
build job: 'Downstream_admin_job', parameters: [string(name: 'UPSTREAM_PARAMS', value:"${UPSTREAM_PARAMS}")]
}
}
stage('Launch job sanity'){
agent any
environment {
UPSTREAM_PARAMS = "${SRC},${AGV}"
}
steps {
build job: 'Downstream_sanity_job', parameters: [string(name: 'UPSTREAM_PARAMS', value:"${UPSTREAM_PARAMS}")]
}
}
}
}
if (TOOL_FILES == '0' ) {
build job: 'Test_verification_job', parameters: [string(name: 'UPSTREAM_PARAMS', value:"${UPSTREAM_PARAMS}")]
}
}
}
}
但我不確定這里有什么問題。不支持在“腳本”塊內啟動并行作業。得到以下錯誤。

有幾件事不清楚。我們可以在另一個階段的“步驟”塊內再次啟動“腳本”塊中的并行階段嗎？
uj5u.com熱心網友回復：
您用于并行命令的語法是宣告性語法，但您在script需要腳本化語法的塊中使用它，因此是例外。
在您的script塊中，您應該使用并行命令的腳本化語法：
并行：并行執行從分支名稱到閉包的映射和一個可選引數 failFast > 它將在任何其他分支失敗時終止所有分支：
parallel firstBranch: { // do something }, secondBranch: { // do something else }, failFast: true|false
因此，在您的情況下，您可以使用以下腳本語法：
parallel(
'Launch JOB admin' : {
node {
build job: 'Downstream_admin_job', parameters: [string(name: 'UPSTREAM_PARAMS', value: "${SRC},${AGV}")]
}
},
'Launch job sanity': {
node {
build job: 'Downstream_sanity_job', parameters: [string(name: 'UPSTREAM_PARAMS', value: "${SRC},${AGV}")]
}
}
)
或者，您可以嘗試script通過將if陳述句替換為宣告性when閉包來避免使用該塊，然后您可以使用當前的語法。
