Problem looping through the result of findFiles.
The result from this method returns a
org.jenkinsci.plugins.pipeline.utility.steps.fs.FileWrapper
node {
stage("Publish") {
def files = findFiles(glob: '**/*.rpm')
for (def file : files) {
sh "echo Hello World! ${file.path}"
}
}
Fails with java.io.NotSerializableException: java.util.AbstractList$Itr
Trying to use @NonCPS
node {
stage("Publish") {
def files = findFiles(glob: '**/*.rpm')
loopFiles(files)
}
}
@NonCPS
void loopFiles(files) {
for (def file : files) {
sh "echo Hello World! ${file.path}"
}
}
It breaks the loop after first item in list. If 3 files found, then there
is only one output.
However, if I remove the shell script and just use println it loops through
all 3 files found.
Works if I loop the files first and put the file path in a new list:
node {
stage("Publish") {
def files = findFiles(glob: '**/*.rpm')
def packages = []
for (def file : files) {
packages.add(file.path)
}
for (def packagePath : packages) {
sh "echo Hello World! ${packagePath}"
}
}
I reckon that FileWrapper is not serializable, hence the problem, but why
doesn't the @NonCPS work on all items?
