| I have a set of steps which share a configuration instance. The configuration is implemented as Singleton. Now, I would like to serialize this @Singleton to support the resume feature of Jenkins pipelines. Currently, all runtime configurations are gone, if the Jenkins is restarted in between. Since statics aren't serialized, I implemented readObject and writeObject. What ever I tried, i came across the ProxyException:
hudson.remoting.ProxyException: CpsCallableInvocation{methodName=writeObject, call=com.cloudbees.groovy.cps.impl.CpsFunction@1bc872bf, receiver=my.simple.TestPipelineEnvironment@40f84a32, arguments=[org.jboss.marshalling.river.RiverObjectOutputStream@8ad5752]}
In the code below, I implemented the simple POGO my.simple.TestPipelineEnvironment.groovy with readObject and writeObject. I dropped the @Singleton to reduce complexity.
package my.simple;
public class TestPipelineEnvironment implements Serializable {
private void writeObject(ObjectOutputStream oos) throws IOException {
System.out.println("Custom serialization logic invoked.");
oos.defaultWriteObject();
}
private void readObject(ObjectInputStream ois) throws IOException, ClassNotFoundException {
System.out.println("Custom deserialization logic invoked.");
ois.defaultReadObject();
}
private Map valueMap = [:]
void setValue(String property, value) {
valueMap[property] = value
}
def getValue(String property) {
return valueMap.get(property)
}
}
It is initialized and accessible by the step vars/testPipelineEnvironment.groovy
import my.simple.TestPipelineEnvironment
class testPipelineEnvironment implements Serializable {
private static final long serialVersionUID = -113665469917946598L;
private TestPipelineEnvironment instance= new TestPipelineEnvironment();
private TestPipelineEnvironment getCPE() {
return instance;
}
Map getValueMap() {
getCPE().valueMap
}
void setValue(String property, value) {
valueMap[property] = value
}
def getValue(String property) {
return valueMap.get(property)
}
}
The Jenkinsfile fails
@Library('piper-lib-rodibrin') _
node() {
stage('prepare') {
testPipelineEnvironment.setValue("key","value") echo "value:" + testPipelineEnvironment.getValue("key")
}
}
with
...
[Pipeline] echo
value:value
[Pipeline] }
[Pipeline] End of Pipeline
