I would like to use the Gradle Copy task, and to specify several files to include from the given directory.
I have seen the syntax with several include directives:
task myTask (type: Copy) {
from: myDir {
include "file1.txt"
include "file2.csv"
include "file3.xml"
}
into: dest
}
But I would like to do that in one line, so that I can use a variable I receive as argument of the include directive.
The syntax is simply to pass an array of Strings:
task myTask (type: Copy) {
from: myDir {
include ["file1.txt", "file2.csv", "file3.xml", "**/otherfile", "*.java"]
}
into: dest
}

Using Gradle typed task how can we exclude file copy for file names starting with as well as ending with some strings?
def contentSpec = copySpec {
exclude {
it.file.name.startsWith('img')
it.file.name.endsWith('gif')
}
from 'src'
}
task copyImages (type: Copy) {
with contentSpec
into 'Dest'
}
On running gradle copyImages, it excludes files ending with gif, but does not exclude files starting with img.
Is there a way to achieve both?
You forgot an or (||) between your two conditions:
exclude { it.file.name.startsWith('img') || it.file.name.endsWith('gif') }
The value of a closure is the value of its last expression. Since the last expression, in your code, is it.file.name.endsWith('gif'), that's the value of the closure, and the file is thus excluded when it.file.name.endsWith('gif') is true.
Of course, you could also use two exclusions:
exclude {
it.file.name.startsWith('img')
}
exclude {
it.file.name.endsWith('gif')
}
What's the most concise and most elegant and the shortest way to copy just one file AND rename it with gradle?
So far I could think of just this:
copy {
from projectDir
into projectDir
include '.env.template'
rename '.env.template', '.env'
}
You can simplify your CopySpec:
copy {
from file('.env.template')
into projectDir
rename '.*', '.env'
}
The from method accepts single File objects and, since only this one file is copied, the rename pattern can match any copied file.
This way is simple and clean, but to follow the Gradle concept, you should consider using a Copy task, to maintain a clean cut between configuration and execution phase.
Edit:
I just learned, that one can provide a closure for the rename method, so you could also use:
copy {
// ...
rename { '.env' }
}
task copySingleFileInGradle {
doFirst {
def src = new File("sourcefile") // this must exist in top-level project dir
def dst = new File("destinationFile") // this will get created when task is run
dst.write(src.text)
}
}
I'm trying to do some processing on some source before moving it to the build directory. Specifically, for files with a .template name, replace instances of #timestamp# with the timeStamp variable i've defined. Additionally, for .jsp files, I would like to remove whitespace between tags.
The first part of this, replacing the timestamp works. Replacing the whitespace in the jsps does not.
processResources {
def timeStamp = Long.toString(System.currentTimeMillis())
from ('../src/resources/webapp') {
include '**/*.template'
filter {
it.replace('#timestamp#', timeStamp)
}
rename '(.*)\\.template', '$1'
}
from ('../src/resources/webapp') {
include '**/*.jsp'
filter {
it.replace('>\\s+<', '><')
}
}
}
Previous to using processResources, I had done something like this for the minification:
task minifyJSPs(type: Copy) {
from ('../src/resources/webapp') {
include '**/*.jsp'
filter {
it.replace('>\\s+<', '><')
}
}
into 'gbuild'
}
Filtering the files like this using copy worked, however, I noticed I wasn't able to copy from a location to itself -- the file would end up empty. This meant that I had to copy files from one intermediate directory to another, applying a filter at each step.
I want to be able to apply various transformations to my source in one step. How can I fix my processResources task?
Suppose you have something like:
task zip(type: Zip) {
archiveName = "out.zip"
duplicatesStrategy = 'exclude'
into('TARGET_FOLDER_IN_ZIP') {
from("$rootDir/customizations/folder1")
from("$rootDir/customizations/folder2")
}
}
According to http://www.gradle.org/docs/current/javadoc/org/gradle/api/file/DuplicatesStrategy.html Exclude means
Do not allow duplicates by ignoring subsequent items to be created at the same path.
So if you have the same filename in folder1 & folder2 only the file from folder1 should end up in the zip. If you change the two "from" lines in the buildfile, only the file from folder2 should end up there. This seems not to be whats happening (gradle 1.10). Instead always the same file is used. Seems like nested "from"s do not preserve their order.
The only solution I've found is to split up the conflicting parts:
into('TARGET_FOLDER_IN_ZIP') {
from("$rootDir/customizations/folder1")
}
into('TARGET_FOLDER_IN_ZIP') {
from("$rootDir/customizations/folder2")
}
now the order is preserved and the output is deterministic
I have a tree of files that I'd like to copy with Gradle, and for some of the files (e.g. ending in .txt), I'd like to do some property substitions. For example, I have:
task "copyAndroidAssets$flavor" (type: Copy,
dependsOn: ["cleanAndroidAssets", "copyAndroidRes$flavor"] ) {
from "build/assets/${flavorLc}/release/"
into '../android/assets'
expand ( versionName: myVersionName, versionCode: myVersionCode )
}
The problem is that some of the files in the tree being copied have dollar signs ($) in them that have nothing to do with property expansion, and this creates the error SimpleTemplateScript6.groovy: 1: illegal string body character after dollar sign;.
In my specific scenario, all the files except one can simply be copied as is. Only a single file, about.txt, needs to have values substituted. Any suggestions on a simple way to do this?
Now (Gradle 2.3.1) there is a better solution: https://issues.gradle.org/browse/GRADLE-1566
processResources {
inputs.property('version', version)
filesMatching("**/version.properties") {
expand version: version
} }
In my case I want project properties expansion only in yaml files:
processResources {
filesMatching("**/*.yaml") {
expand project.properties
}
}
Thanks to the link from Opal in the comments, I found a solution. The link shows that it is possible to have multiple from sources and each of these can have a separate expand treatment. Thus, in my case, I only wanted to expand .txt files, so I split the from into two parts using include & exclude as follows:
task "copyAndroidAssets$flavor" (type: Copy,
dependsOn: ["cleanAndroidAssets", "copyAndroidRes$flavor"] ) {
from ("build/assets/${flavorLc}/release/") {
include '**/*.txt'
expand ( versionName: versionName, versionCode: versionCode )
}
from ("build/assets/${flavorLc}/release/") {
exclude '**/*.txt'
}
into '../android/assets'
expand ( versionName: myVersionName, versionCode: myVersionCode )
}
