问题
I have the Jenkins shared library with the following structure:
resources
|-> config.yaml
|-> projects.yaml
src
|_ com
|_ rathath
|_ jenkins
|-> Configuration.groovy
In src/com/rathath/jenkins/Configuration.groovy , I want to read YAML files in resources directory.
I tried :
@Grab('org.yaml:snakeyaml:1.17')
import org.yaml.snakeyaml.Yaml
import hudson.FilePath
// ...
def readConfig() {
def config = [:]
def cwd = hudson.model.Executor.currentExecutor().getCurrentWorkspace().absolutize()
new FilePath(cwd, 'resources').list('*.yaml').each {
config << it.read()
}
}
Unfortunately, i got hudson.model.Executor.currentExecutor()
is null.
I tried another way:
@Grab('org.yaml:snakeyaml:1.17')
import org.yaml.snakeyaml.Yaml
import hudson.FilePath
import groovy.transform.SourceURI
import java.nio.file.Paths
// ...
@SourceURI
URI source Uri
def readConfig() {
def config = [:]
def cwd = new FilePath(Paths.get(sourceUri).getParent().getParent().getParent().getParent().getParent().getParent().toFile());
new FilePath(cwd, 'resources').list('*.yaml').each {
config << it.read()
}
}
I got bigger issue,.. Jenkins was not able to load the file :
java.lang.NoClassDefFoundError: Could not initialize class com.rathath.jenkins.Configuration
at java.io.ObjectStreamClass.hasStaticInitializer(Native Method).
.....
....
回答1:
I guess you are calling your file src/com/rathath/jenkins/Configuration.groovy
from vars/whateverPipelineFile.groovy
so, when calling it, make sure you pass pipeline context and, from your class you will be able to use context.libraryResource()
Example:
Configuration.groovy
class Configuration {
def context
Configuration(pipelineContext) {
this.context = pipelineContext
}
def readConfig() {
this.context.libraryResource("${PATH_OF_YOUR_FILE}")
...
}
}
/vars/myPipeline.groovy
import com.rathath.jenkins.configuration.Configuration
def call() {
def configuration = new Configuration(this)
configuration.readConfig()
...
}
Documentation of libraryResource() here

It was not easy to get it working. But i did it:
In src/com/rathath/jenkins/Configuration.groovy
:
@Grab(group='org.yaml', module='snakeyaml', version='1.17')
import org.yaml.snakeyaml.Yaml
import java.io.File
import groovy.transform.SourceURI
import java.nio.file.Path
import java.nio.file.Paths
import static groovy.io.FileType.*
class Configuration {
Map config = [:]
@SourceURI
URI sourceUri
Configuration() {
new File(getRootLocation(), 'resources')
.eachFileMatch(FILES, ~/.*\.yaml/) {
this.config << yaml.load(it.text)
}
}
@NonCPS
File getRootLocation() {
return Paths.get(sourceUri)
.getParent() // jenkins
.getParent() // rathath
.getParent() // com
.getParent() // src
.getParent() // .
.toFile()
}
}
