Jenkins Groovy腳本

Question

我有一個名爲MyTests的布爾參數作爲構建作業的一部分。該作業調用Groovy腳本。我相信下面的特定代碼在腳本中引起了一個問題。任何想法在Groovy中引用if語句中的布爾值的正確方法。

stage("post_build") { 
    if (${params.MyTests}) { 
     my_code_block... 
     } 

java.lang.NoSuchMethodError: No such DSL method '$' found among steps

Answer 1

取出${...}並直接寫入param.MyTests。 ${...}只能在引用變量（或常規groovy/java表達式）內部的字符串時使用。所以：

def foo = "bar" 
echo foo 
echo "Withing a string: ${foo}" 

所以你的情況：

stage("post_build") { 
    if (params.MyTests) { 
     my_code_block... 
    } 
    ... 

Answer 2

見Pipeline Syntax, Flow Control：

stage('Example') { 
    if (env.BRANCH_NAME == 'master') { 
     echo 'I only execute on the master branch' 
    } 
} 

和JENKINS-27295：

I would say that it is a best practice to always use the params object if you want the ensure that the type is consistent. Referencing the parameter as either foo or env.foo returns the value as it was injected into an environment variable and will always be of type String .

properties([parameters([booleanParam(defaultValue: false, description: '', name: 'foo')])]) 

echo "foo: " + foo.getClass().toString() 
echo "env.foo: " + env.foo.getClass().toString() 
echo "params.foo: " + params.foo.getClass().toString() 

returns:

[Pipeline] echo 
foo: class java.lang.String 
[Pipeline] echo 
env.foo: class java.lang.String 
[Pipeline] echo 
params.foo: class java.lang.Boolean 
[Pipeline]
