I am trying to fix the args-argument for the executing programm for this Gradle task:
task generateResources(type: JavaExec) {
group = 'build'
description = 'Generate resource bundle from excel file'
mainClass.set('com.project.MainClass')
ext {
destDir = ''
sourceFile = ''
isDir = false
setInputDir = { input ->
xlxsTree = fileTree(input).matching { include '*.xls' }
xlxsTree.files.each {
args[1] = "$it" //how can I add all matching files???
}
}
setOutput = { output ->
outputs.dir(output)
destDir = output
args[0] = destDir
}
}
setInputDir("${project.projectDir}\\src\\main\\resources\\properties")
setOutput("${project.buildDir}\\resources\\generatedProperties")
logging.captureStandardOutput LogLevel.INFO
onlyIf {
!sourceFile.empty
}
classpath = project.configurations.resbundles
doFirst {
args args
jvmArgs '-Dfile.encoding=ISO-8859-15'
}
The args-argument in doLast{} should contain all file paths ending with .xls, e. g. ["C:\...\src\main\resources\properties\destdir", "C:\...\resources\generatedProperties\file1", "C:\...\resources\generatedProperties\file2"].
My approach is not working at all, I just tried to make it compile for at least one input file.
I have a Gradle rule like:
tasks.addRule("Pattern: updatelight<Path> (copies files to ../<Path>).") { String taskName ->
if (taskName.startsWith("updatelight")) {
task([ "type": Copy ], taskName) {
def projectGroups = (sub + root)
def testEnvPath = taskName - 'updatelight'
into ("../${testEnvPath}/")
logger.info("Copies user.xml")
projectGroups.each { project ->
if (!project.isEmpty()) {
from (project.output) {
into "cfg/${project.newPath}"
eachFile { file ->
println " ${file.sourcePath} -> ${file.path}"
println '----------------------------------------------'
}
}
}
}
[...]
My problem is, eachFile { ... } is not printing to console. Any hint? I am a Gradle-newbie and just try to add some logging to the existing task.
There was no problem with the code. Because of cache there were to actions taken therefore no logging.
I have a Gradle build file which uses ProtoBuffer plugin and runs some tasks. At some point some tasks are run for some files, which are inputs to tasks.
I want to modify the set of files which is the input to those tasks. Say, I want the tasks to be run with files which are listed, one per line, in a particular file. How can I do that?
EDIT: Here is a part of rather big build.gradle which provides some context.
configure(protobufProjects) {
apply plugin: 'java'
ext {
protobufVersion = '3.9.1'
}
dependencies {
...
}
protobuf {
generatedFilesBaseDir = "$projectDir/gen"
protoc {
if (project.hasProperty('protocPath')) {
path = "$protocPath"
}
else {
artifact = "com.google.protobuf:protoc:$protobufVersion"
}
}
plugins {
...
}
generateProtoTasks {
all().each { task ->
...
}
}
sourceSets {
main {
java {
srcDirs 'gen/main/java'
}
}
}
}
clean {
delete protobuf.generatedFilesBaseDir
}
compileJava {
File generatedSourceDir = project.file("gen")
project.mkdir(generatedSourceDir)
options.annotationProcessorGeneratedSourcesDirectory = generatedSourceDir
}
}
The question is, how to modify the input file set for existing task (which already does something with them), not how to create a new task.
EDIT 2: According to How do I modify a list of files in a Gradle copy task? , it's a bad idea in general, as Gradle makes assumptions about inputs and outputs dependencies, which can be broken by this approach.
If you would have added the gradle file and more specific that would have been very helpful. I will try to give an example from what I have understood:
fun listFiles(fileName: String): List<String> {
val file = file(fileName).absoluteFile
val listOfFiles = mutableListOf<String>()
file.readLines().forEach {
listOfFiles.add(it)
}
return listOfFiles
}
tasks.register("readFiles") {
val inputFile: String by project
val listOfFiles = listFiles(inputFile)
listOfFiles.forEach {
val file = file(it).absoluteFile
file.readLines().forEach { println(it) }
}
}
Then run the gradle like this: gradle -PinputFile=<path_to_the_file_that_contains_list_of_files> readFiles
Hi I got this zip task which works great:
def dir = new File("${projectDir.parentFile}/test/")
task testZip(type: Zip) {
from dir
destinationDirectory = dir
include 'toast/**'
archiveFileName = 'test.zip'
}
but then when I make the include property lazy (because I need to in my real case)
def dir = new File("${projectDir.parentFile}/test/")
task testZip(type: Zip) {
from dir
destinationDirectory = dir
include {
'toast/**'
}
archiveFileName = 'test.zip'
}
then it creates a zip that includes everything in the folder, (so the generated archive too). In this test case the inner zip is just corrupted (doesn't run infinitely) but in the real world case it does make an infinite zip. (Not sure why, maybe my best case has too few or small files). Either way the test case shows the problem, the generated zip contains a zip even though it should only contain the toast directory and all of its content.
How do I fix this? I need a lazy include because the directory I want to include is computed by other tasks. I get the exact same problem with Tar except it refuses to create the archive since it includes itself.
Using exclude '*.zip' is a dumb workaround which makes the archive include other folders I don't want. I only want to include a specific folder, lazyly.
Here's what the monster looks like in the real world case. I basically need to retrieve the version of the project from Java to then use that version to name the folders I'm packaging. (Making a libGDX game and packaging it with a jre using packr). The problematic tasks are 'makeArchive_' + platform.

You can get what you want by using the doFirst method and modifiying the tasks properties with the passed action.
task('makeArchive_' + platform, type: Zip) {
if(platform.contains("win"))
dependsOn setWindowsIcons
dependsOn fetchVersion
dependsOn 'packr_' + platform
from packrDir
destinationDirectory = packrDir
archiveFileName = provider {
platformRawName.replace("%%VERSION%%", jumpaiVersion) + ".zip"
}
doFirst {
def includeDir = platformRawName.replace("%%VERSION%%", jumpaiVersion)
// Include only files and directories from 'includeDir'
include {
it.relativePath.segments[ 0 ].equalsIgnoreCase(includeDir)
}
}
}
Please have also a look at this answer to a similar question. My solution is just a workaround. If you know your version at configuration phase you can achieve what you want more easily. Writing your own custom tasks or plugins can also help to clean up your build script.
Gradle copySpec include closure not working:
def fileList = ["hello/world.xml"]
task foo(type: Copy) {
from (zipTree("/path/a.zip")) {
include { elem ->
fileList.contains(elem.path)
}
}
}
The a.zip contains "hello/world.xml".
Message:
Skipping task 'foo' as it has no source files and no previous output files.
A copySpec closure needs to be used with a copy task.
Your code is just the copy task, which requires a destination to copy into.
Your code should be more like this:
def fileList = ["hello/world.xml"]
def filesToCopy = copySpec {
from (zipTree("/path/a.zip")) {
include { elem ->
fileList.contains(elem.path)
}
}
}
task foo(type: Copy) {
into 'build/target/docs'
with filesToCopy
}
