Jenkins工作流程：基於工具輸出的並行化步驟

我想基於測試工具的輸出並行化Jenkins階段。但是，我遇到了一個問題，因爲所有並行節點的定義都是一樣的（除了jenkins-workflow插件中的currently broken循環外）。下調的工作流程腳本示例：Jenkins工作流程：基於工具輸出的並行化步驟

instances = ["one", "two", "three"] 
print "Testing instances: " + instances 

test_nodes = [:] 
for (int i = 0; i < instances.size(); i++) { 
    instance_name = instances.get(i) 
    println "Processing instance " + instance_name 
    test_nodes["tk-${instance_name}"] = { 
    node { 
     stage name: ('stage ' + instance_name) 
     echo instance_name 
    } 
    } 
} 
echo "test_nodes: ${test_nodes}" 
parallel test_nodes

雖然我希望結果如下：

node { 
    stage name: 'stage one' 
    echo 'one' 
}, 
node { 
    stage name: 'stage two' 
    echo 'two' 
}, 
node { 
    stage name: 'stage three' 
    echo 'three' 
}

我得到的所有三個節點定義爲 - 因爲它可以在可見以下輸出（注意重複輸出three）：

[Pipeline] echo 
Testing instances: [one, two, three] 
[Pipeline] echo 
Processing instance one 
[Pipeline] echo 
Processing instance two 
[Pipeline] echo 
Processing instance three 
[Pipeline] echo 
test_nodes: [tk-one:[email protected], tk-two:[email protected], tk-three:[email protected]] 
[Pipeline] Execute in parallel : Start 
[Pipeline] [tk-one] parallel { (Branch: tk-one) 
[Pipeline] [tk-two] parallel { (Branch: tk-two) 
[Pipeline] [tk-three] parallel { (Branch: tk-three) 
[Pipeline] [tk-one] Allocate node : Start 
[tk-one] Running on master in /var/lib/jenkins/jobs/cookbook-pipeline-cookbook-site-mstypo3org/workspace 
[Pipeline] [tk-two] Allocate node : Start 
[tk-two] Running on master in /var/lib/jenkins/jobs/cookbook-pipeline-cookbook-site-mstypo3org/[email protected] 
[Pipeline] [tk-three] Allocate node : Start 
[tk-three] Running on master in /var/lib/jenkins/jobs/cookbook-pipeline-cookbook-site-mstypo3org/[email protected] 
[Pipeline] [tk-one] node { 
[Pipeline] [tk-two] node { 
[Pipeline] [tk-three] node { 
[Pipeline] [tk-one] echo 
[tk-one] three 
[Pipeline] } //node 
[Pipeline] [tk-two] echo 
[tk-two] three 
[Pipeline] } //node 
[Pipeline] [tk-three] echo 
[tk-three] three 
[Pipeline] } //node 
[Pipeline] Allocate node : End 
[Pipeline] Allocate node : End 
[Pipeline] Allocate node : End 
[Pipeline] } //parallel 
[Pipeline] } //parallel 
[Pipeline] } //parallel 
[Pipeline] Execute in parallel : End 
[Pipeline] End of Pipeline

這是怎麼發生的？這是workflow-cps中的另一個錯誤，還是我錯了？ parallel example不訪問任何變量。

嘗試def instance_name = instances.get(i)

沒有它，它就像你只需要將INSTANCE_NAME，其在循環之後最終成爲一個引用。其相同的對象，該對象的方式..

結果：

[Pipeline] echo 
Testing instances: [one, two, three] 
[Pipeline] echo 
Processing instance one 
[Pipeline] echo 
Processing instance two 
[Pipeline] echo 
Processing instance three 
[Pipeline] echo 
test_nodes: [tk-one:[email protected], tk-two:[email protected], tk-three:[email protected]] 
[Pipeline] Execute in parallel : Start 
[Pipeline] [tk-one] parallel { (Branch: tk-one) 
[Pipeline] [tk-two] parallel { (Branch: tk-two) 
[Pipeline] [tk-three] parallel { (Branch: tk-three) 
[Pipeline] [tk-one] Allocate node : Start 
[tk-one] Running on master in /var/lib/jenkins/jobs/pipeline/workspace 
[Pipeline] [tk-two] Allocate node : Start 
[tk-two] Running on master in /var/lib/jenkins/jobs/pipeline/[email protected] 
[Pipeline] [tk-three] Allocate node : Start 
[Pipeline] [tk-one] node { 
[Pipeline] [tk-two] node { 
[tk-three] Running on master in /var/lib/jenkins/jobs/pipeline/workspace 
[Pipeline] [tk-one] stage (stage one) 
[tk-one] Entering stage stage one 
[tk-one] Proceeding 
[Pipeline] [tk-one] echo 
[tk-one] one 
[Pipeline] } //node 
[Pipeline] [tk-two] stage (stage two) 
[tk-two] Entering stage stage two 
[tk-two] Proceeding 
[Pipeline] [tk-two] echo 
[tk-two] two 
[Pipeline] } //node 
[Pipeline] Allocate node : End 
[Pipeline] [tk-three] node { 
[Pipeline] Allocate node : End 
[Pipeline] } //parallel 
[Pipeline] } //parallel 
[Pipeline] [tk-three] stage (stage three) 
[tk-three] Entering stage stage three 
[tk-three] Proceeding 
[Pipeline] [tk-three] echo 
[tk-three] three 
[Pipeline] } //node 
[Pipeline] Allocate node : End 
[Pipeline] } //parallel 
[Pipeline] Execute in parallel : End 
[Pipeline] End of Pipeline 
Finished: SUCCESS
