In gradle I want to use a directory variable, what in ant would be ${mydir}.
def mydir = new File("mydir")
copy {
from 'example.txt'
into '${mydir}/out/'
}
How to do this? The docs don't contain information on this issue AFAICS, http://gradle.org/docs/current/userguide/working_with_files.html
Try:
into new File(mydir, out)
or if with GString
into "${mydir}/out/"
(note the double " quotes)

I'm trying to use variables declared in bash script in my Jenkinsfile (jenkins pipeline) without using extra plugins like EnvInject plugin
please help, any idea will be appreciated
you need to output those variables to a file like Property/Yaml file. Then use pipeline step readProperties / readYaml to read into Map in Jenkinsfile.
steps {
sh'''
...
AA=XXX
BB=YYY
set > vars.prop
'''
script {
vars = readProperties file: 'vars.prop'
env << vars // merge vars into env
echo 'AA='+ env['AA']
}
}
I have done it with something like this, you can store the variables inside Shell into a file inside workspace and then you are out of shell block, read the file in groovy to load the key value pair into your environment
Something like:
def env_file = "${WORKSPACE}/shell_env.txt"
echo ("INFO: envFileName = ${env_file}")
def read_env_file = readFile env_file
def lines = read_env_file.readLines()
lines.each { String line ->
def object = line.split("=")
env.object[0] = object[1]
}
The error message:
* What went wrong:
A problem occurred evaluating root project 'telescope-master'.
> Cannot get property 'dir' on null object
gradle.properties file
classes.dir = WebContent/WEB-INF/classes
webContent.dir = WebContent
template.dir = hdm/template
javascript.dir = hdm/function
javascript4.0.2.dir = hdm/function/4.0.2
datamodel.dir = hdm/datamodel
certificate.dir = certificate
build.gradle file
Properties extFile = new Properties()
extFile.load(new FileInputStream('gradle.properties'))
task FirmwareMatch(type: Zip) {
from ("${extFile.javascript.dir}")
include 'factoryResetOnFirmwareMatch.*'
archiveName 'factoryResetOnFirmwareMatch.zip'
destinationDir file('dist/hdm/function')
}
So basically if I remove the "." from .dir on both files it would work. But is there any way to over ride it?
Also how can I display actual date when using ${TODAY} in gradle.
So your problematic expression is:
extFile.javascript.dir
If we break that into how Groovy will interpret it:
extFile.getProperty('javascript').getProperty('dir')
You want Groovy to interpret it as:
extFile.getProperty('javascript.dir')
Besides directly calling getProperty, here are a couple Groovy options:
extFile.'javascript.dir'
extFile['javascript.dir']
Additionally, assuming your gradle.properties file is either in your project root (generally as a sibling to the build.gradle) or in your GRADLE_HOME directory (i.e. ~/.gradle/gradle.properties) it will be automatically loaded by Gradle and all properties available as project properties.
So you can remove all of your properties parsing code and just do the following:
project.getProperty('javascript.dir')
// or
project.'javascript.dir'
// or
project['javascript.dir']
If you want to protect against those properties not being set, and are on Gradle 2.13 or higher, you can use findProperty instead of getProperty which will return null instead of throwing an exception.
I want to replace a value in our log4j2.xml with Gradle during build. I found a way to do that:
task reaplaceInLogFile {
String apiSuffix = System.properties['apiSuffix'] ?: ''
println "In my task"
String contents = file('src/main/resources/log4j2.xml').getText( 'UTF-8' )
println "File found"
contents = contents.replaceAll( "svc0022_operations", "svc0022_operations${apiSuffix}")
new File( 'src/main/resources/log4j2.xml' ).write( contents, 'UTF-8' )
}
However, this changes also the source file permanently and I do not want to do that. I want to change the log4j2.xml that will be included in the build zip only. I know I can use something like this:
tasks.withType(com.mulesoft.build.MuleZip) { task ->
String apiSuffix = System.properties['apiSuffix'] ?: ''
task.eachFile {
println name
if (name == 'mule-app.properties') {
println "Expanding properties for API Version suffix: ${apiSuffix}"
filter { String line ->
line.startsWith("${serviceId}.api.suffix") ? "${serviceId}.api.suffix=${apiSuffix}" : line
}
}
But I do not know what is the type of the log4j2 file. If there is another way to do that I will be thankful!
We are using Mule gradle plugin.
The Type is not the type of the log4j2 file, but the type of the task that creates the ZIP or wherever your log4j2 file is packaged into. If the log4j2 file is included in the ZIP that is generated by a MuleZip task, then you can simply add another if-branch for the log4j2 file.
But actually it is probably better to just edit the concrete task that packages up the log4j2 file into some archive instead of all tasks of the same type.
Besides that you should be able to use filesMatching instead of eachFile with an if I think.
I am developing an Android application where I have a directory of JSON files and I want to create a gradle task that will combine all these files into a single JSON file.
This is the gradle task I have so far but does not create the file:
// Task that combines all JSON files in ../libraries into src/main/res/raw/libraries.json
task combineJSonFiles {
String content = ""
FileTree tree = fileTree(dir: '../libraries', include: '**/*.json')
tree.each {File file ->
content += file.getText()
}
println "[" + content.substring(0, content.length()-1) + "]" // prints out the correct contents
File libraries = file("../app/src/main/res/raw/libraries.json")
println libraries.getProperties()
}
I print out the properties and I am not sure why these are the property values:
{directory=false, canonicalFile=/Users/michaelcarrano/AndroidStudioProjects/detective_droid/app/src/main/res/raw/libraries.json, file=false, freeSpace=0, canonicalPath=/Users/michaelcarrano/AndroidStudioProjects/detective_droid/app/src/main/res/raw/libraries.json, usableSpace=0, hidden=false, totalSpace=0, path=/Users/michaelcarrano/AndroidStudioProjects/detective_droid/app/src/main/res/raw/libraries.json, name=libraries.json, prefixLength=1, absolute=true, class=class java.io.File, parentFile=/Users/michaelcarrano/AndroidStudioProjects/detective_droid/app/src/main/res/raw, absolutePath=/Users/michaelcarrano/AndroidStudioProjects/detective_droid/app/src/main/res/raw/libraries.json, absoluteFile=/Users/michaelcarrano/AndroidStudioProjects/detective_droid/app/src/main/res/raw/libraries.json, parent=/Users/michaelcarrano/AndroidStudioProjects/detective_droid/app/src/main/res/raw}
Any help is appreciated as I have not seemed to figure this out even after reading the documentation. http://www.gradle.org/docs/current/userguide/working_with_files.html
I am just posting the code for the task that now works:
task combineJSonFiles {
String content = ""
FileTree tree = fileTree(dir: '../libraries', include: '**/*.json')
tree.each {File file ->
content += file.getText()
}
def libraries = new File("app/src/main/res/raw/libraries.json")
libraries.text = "[" + content.substring(0, content.length()-1) + "]"
}
My issue was trying to use Java.io.File and having the wrong directory path set for my file.
Creating an instance of java.io.File in Groovy/Java does not create the file on disk. You will need to write something to it. Check out this tutorial for working with files in Groovy.
Also you have put your task implementation in a task configuration block, rather than a task action. This means your code will not be running when you are expecting - it will run every time you run gradle rather than when you run this task. You need to put your code in a doLast block
I can execute a pom.xml with goals using AntBuilder like so.
def ant = new AntBuilder()
ant.sequential {
exec(executable:'mvn') {
arg(value:'clean')
arg(value:'install')
}
}
But how do I specify the execution directory to the AntBuilder? I'd like to just pass an absolute path.
For the record I've tried.
ant.project.setProperty('basedir', "${serviceRootDir}/")
and
ant.sequential {
mkdir(dir:"${serviceRootDir}/")...
You'd think this would be clear in the doc.
This works for me:
ant.exec(executable:"ls", dir:"/your/desired/directory")
It executes ls in the given directory, so mvn should work.
