Nice question, the surprising thing about the code above is that println “${‘test’}”.equals(‘test’) returns false. The other line of code returns the expected result, so let’s forget about that. Summary “${‘test’}”.equals(‘test’) The object that equals is called on is of type GStringImpl whereas ‘test’ is of type String, so they are not considered equal. But … Read more
I realize this question was about creating a plugin, but since the new Jenkins 2 Pipeline builds use Groovy, I found myself here while trying to figure out how to read a file from a workspace in a Pipeline build. So maybe I can help someone like me out in the future. Turns out it’s … Read more
The trick was to use a list: println([‘ls’, ‘/tmp/folder with spaces’].execute().text)
With a declarative Jenkinsfile, you can use following pipeline: pipeline { agent any stages { stage (‘push artifact’) { steps { sh ‘mkdir archive’ sh ‘echo test > archive/test.txt’ zip zipFile: ‘test.zip’, archive: false, dir: ‘archive’ archiveArtifacts artifacts: ‘test.zip’, fingerprint: true } } stage(‘pull artifact’) { steps { copyArtifacts filter: ‘test.zip’, fingerprintArtifacts: true, projectName: env.JOB_NAME, … Read more
Use the toInteger() method to convert a String to an Integer, e.g. int value = “99”.toInteger() An alternative, which avoids using a deprecated method (see below) is int value = “66” as Integer If you need to check whether the String can be converted before performing the conversion, use String number = “66” if (number.isInteger()) … Read more
It’s syntactic sugar for basic scripts. Omitting the “def” keyword puts the variable in the bindings for the current script and groovy treats it (mostly) like a globally scoped variable: x = 1 assert x == 1 assert this.binding.getVariable(“x”) == 1 Using the def keyword instead does not put the variable in the scripts bindings: … Read more
It looks to me you complicate things too much. Here’s a simple example that should do the job: For given test.properties file: a=1 b=2 This code runs fine: Properties properties = new Properties() File propertiesFile = new File(‘test.properties’) propertiesFile.withInputStream { properties.load(it) } def runtimeString = ‘a’ assert properties.”$runtimeString” == ‘1’ assert properties.b == ‘2’
If you don’t mind the code in file2 being in a with block, you can do: new GroovyShell().parse( new File( ‘file1.groovy’ ) ).with { method() } Another possible method would be to change file1.groovy to: class File1 { def method() { println “test” } } And then in file2.groovy you can use mixin to add … Read more
The plugins block is the newer method of applying plugins, and they must be available in the Gradle plugin repository. The apply approach is the older, yet more flexible method of adding a plugin to your build. The new plugins method does not work in multi-project configurations (subprojects, allprojects), but will work on the build … Read more
In a Groovy script the scoping can be different than expected. That is because a Groovy script in itself is a class with a method that will run the code, but that is all done runtime. We can define a variable to be scoped to the script by either omitting the type definition or in … Read more
