I have read around stackoverflow and the gradle forms, but I am still stumped. The ultimate goal here is that after I copy some files, I want to set the writable flag -- because 'copy' doesn't like overwriting read-only files on 'nix (huh...), nor can it be forced to do so (harumph!).
Here is the outline of what I have:
task setPermissions (type : Exec) {
executable = 'chmod -R +w'
}
// ... a little while later ...
task('somethingElse') << {
// ... unrelated stuff ...
def String targetDir = "$aVar/theTarget"
// >> TASK CALL <<
setPermissions {
commandLine = [executable + " $targetDir"]
}
// but that doesn't work... this does...
proc = Runtime.getRuntime().exec("chmod -R +w $deployDir")
proc.waitFor()
}
I have tried variations in "setPermissions".
Trial 1:
commandLine = 'chmod'
args = '-R', '+w'
In which case I appended the target directory to "args" when I called setPermissions.
Trial 2:
commandLine = 'chmod -R +w'
In which case I appended the target directory to "commandLine" when I called setPermissions. I also tried making it the only "args" value.
Trial 3:
commandLine = 'chmod', '-R', '+w'
In which case I appended the target directory to "commandLine" when I called setPermissions. I also tried making it the only "args" value.
So what am I doing wrong here that an Exec task won't run this properly, but the Rt.gR.exec() will?
You can't call a task from another task. You'll have to make one depend on the other, or call the Project.exec method from a task action. The syntax for configuring the exec method is exactly the same as for the Exec task.
PS: Have you tried to use Copy.fileMode instead of chmod?

I have a gradle build setup at the beginning of which I want to execute a shellscript in a subdirectory that prepares my environment.
task build << {
}
task preBuild << {
println 'do prebuild stuff:'
}
task myPrebuildTask(type: Exec) {
workingDir "$projectDir/mySubDir"
commandLine './myScript.sh'
}
build.dependsOn preBuild
preBuild.dependsOn myPrebuildTask
However, when I execute the task either by calling gradle myPrebuildTask or by simply building the project, the following error occurs:
> A problem occurred starting process 'command './myScript.sh''
Unfortunately, thats all I get.
I have also tried the following - same error.
commandLine 'sh mySubDir/myScript.sh'
I use Gradle 1.10 (needed by Android) on Windows, inside a Cygwin shell. Any ideas?
use
commandLine 'sh', './myScript.sh'
your script itself is not a program itself, that's why you have to declare 'sh' as the program and the path to your script as an argument.
A more generic way of writing the exec task, but portable for Windows/Linux, if you are invoking a command file on the PATH:
task myPrebuildTask(type: Exec) {
workingDir "$projectDir/mySubDir"
if (System.getProperty('os.name').toLowerCase(Locale.ROOT).contains('windows')) {
commandLine 'cmd', '/c', 'mycommand'
} else {
commandLine 'sh', '-c', 'mycommand'
}
}
This doesn't directly address the use case for the OP (since there is script file in the working directory), but the title of the question is more generic (and drew me here), so it could help someone maybe.
unfortunately options with commandLine not worked for me in any way and my friend find other way with executable
executable "./myScript.sh"
and full task would be
task startScript() {
doLast {
exec {
executable "./myScript.sh"
}
}
}
This works for me in my Android project
preBuild.doFirst {
println("Executing myScript")
def proc = "mySubDir/myScript.sh".execute()
proc.waitForProcessOutput(System.out, System.err)
}

How to make System command calls in Java/Groovy?
This is a solution for Kotlin DSL (build.gradle.kts) derived from Charlie Lee's answer:
task<Exec>("MyTask") {
doLast {
commandLine("git")
.args("rev-parse", "--verify", "--short", "HEAD")
.workingDir(rootProject.projectDir)
}
}
Another approach using the Java standard ProcessBuilder API:
tasks.create("MyTask") {
val command = "git rev-parse --verify --short HEAD"
doLast {
val process = ProcessBuilder()
.command(command.split(" "))
.directory(rootProject.projectDir)
.redirectOutput(Redirect.INHERIT)
.redirectError(Redirect.INHERIT)
.start()
process.waitFor(60, TimeUnit.SECONDS)
val result = process.inputStream.bufferedReader().readText()
println(result)
}
}

for kotlin gradle you can use

I copied my shell scipt to /usr/local/bin with +x permission and used it as just another command:

I am trying to do an Xcode build in Gradle. Requirements:
Some of my arguments have spaces in them.
I want to pipe the output through xcpretty. Otherwise gitlab complains that there is too much output and I can't see any errors toward the end of the build
I don't want to wait for the command to complete before seeing the output. I want to be able to watch it build, like any ci job
Gradle exec{} doesn't seem to let me pipe the output while building. I can save the output to a file but that doesn't let me watch the build
I.e.,
exec {
executable 'xcodebuild'
ext.output = {
return standardOutput.toString()
}
args = [
'archive',
'-project',
"${buildDir}/iPhone/Unity-iPhone.xcodeproj/",
"-archivePath",
"${buildDir}/iPhone/Unity-iPhone.xcarchive",
"-sdk", "iphoneos",
"GCC_GENERATE_DEBUGGING_SYMBOLS=YES",
"DEBUG_INFORMATION_FORMAT=dwarf-with-dsym",
"DWARF_DSYM_FILE_SHOULD_ACCOMPANY_PRODUCT=NO",
"DWARF_DSYM_FOLDER_PATH=iOS_Dsym",
"DEBUGGING_SYMBOLS=YES",
"DEVELOPMENT_TEAM=RPGSNMH65P",
"CODE_SIGN_IDENTITY=${appleIdentity}",
"CODE_SIGN_STYLE=Manual",
"USYM_UPLOAD_AUTH_TOKEN=${appcenter_login_token}",
"PROVISIONING_PROFILE_SPECIFIER_APP=${provisioningProfile}",
"-configuration", "Release",
"-scheme", "${schemeName}",
"| xcpretty"
]
}
doesn't work
I can't use groovy "xcodebuild ... CODE_SIGN_IDENTITY=${"${appleIdentity}"} ... | xcpretty".execute() because my code signing identity contains spaces and for some reason groovy wants to stick its own quotes into the command string when it finds spaces.
I tried the array execute method but ended up with the same problem.
def cmd = [
'xcodebuild ',
'archive',
'-project',
"${buildDir}/iPhone/Unity-iPhone.xcodeproj/",
"-archivePath",
"${buildDir}/iPhone/Unity-iPhone.xcarchive",
"-sdk", "iphoneos",
"GCC_GENERATE_DEBUGGING_SYMBOLS=YES",
"DEBUG_INFORMATION_FORMAT=dwarf-with-dsym",
"DWARF_DSYM_FILE_SHOULD_ACCOMPANY_PRODUCT=NO",
"DWARF_DSYM_FOLDER_PATH=iOS_Dsym",
"DEBUGGING_SYMBOLS=YES",
"DEVELOPMENT_TEAM=RPGSNMH65P",
"CODE_SIGN_IDENTITY=${appleIdentity}",
"CODE_SIGN_STYLE=Manual",
"USYM_UPLOAD_AUTH_TOKEN=${appcenter_login_token}",
"PROVISIONING_PROFILE_SPECIFIER_APP=${provisioningProfile}",
"-configuration", "Release",
"-scheme", "${schemeName}"
]
println cmd
def proc = cmd.execute()
... except that it's even harder to debug because I can't see the actual command being executed.
I have found various solutions online but nothing that fits these requirements
I have the following simple task in my build:
task generateFile << {
def file = new File("$buildDir/setclasspath.sh")
file.text = "sample"
outputs.file(file)
}
task createDistro(type: Zip, dependsOn: ['copyDependencies','packageEnvironments','jar', 'generateFile']) <<{
from generateClasspathScript {
fileMode = 0755
into 'bin'
}
}
When I run gradle clean build I see the following output:
Cannot call TaskOutputs.file(Object) on task ':generateFile' after task has started execution. Check the configuration of task ':generateFile' as you may have misused '<<' at task declaration
How do I declare the task file creation outputs as an input to the zip task while also ensuring they happen in the execution phase?
If I leave off the << then the clean task wipes the generated file before the ZIP can use it. If I keep them, I get the above error.
It's the opposite as what is being suggested in the comments. You are trying to set the outputs in execution phase. The correct way to do what you are probably trying to do is for example:
task generateFile {
def file = new File("$buildDir/setclasspath.sh")
outputs.file(file)
doLast {
file.text = "sample"
}
}
I'm trying to write a task rule to create a series of tasks that checkout various svn repository locations. Here is my rule:
tasks.addRule("Pattern: svnCheckout<Classifier> - Checks out the indicated svn repo") { String taskName ->
if(taskName.startsWith('svnCheckout')) {
task(name: taskName, type: Exec) {
String classifier = taskName - 'svnCheckout'
String svnDir = svnRepoUrl //defined elsewhere
switch(classifier) {
case 'SourceTrunk':
svnDir += 'branches/CleanBuild/trunk'
break
case 'AutoInstaller':
svnDir += 'Tools/AutoInstaller'
break
case 'ContentAutomation':
svnDir += 'Tools/ContentAutomation'
break
case 'InternalTools':
svnDir += 'Tools/Internal'
break
default:
throw new GradleException("Invalid svnCheckout classifier '$classifier'")
}
String svnCommand = "svn co $svnDir --trust-server-cert"
//commandLine 'cmd', '/c', "$svnCommand"
commandLine 'cmd', '/c/', "echo 'Task created'"
workingDir = "$workspace"
}
}
}
I then try to run the task 'svnCheckoutSourceTrunk' with this command:
gradlew -Pworkspace="." svnCheckoutSourceTrunk
which fails with the error
FAILURE: Could not determine which tasks to execute.
* What went wrong:
Task 'svnCheckoutSourceTrunk' not found in root project 'GradleScripts'.
* Try:
Run gradlew tasks to get a list of available tasks.
BUILD FAILED
Anyone see what I'm doing wrong? I put some println statements around the first few lines, and the execution is getting past the if statement, but it's not getting inside the task declaration.
The syntax used for declaring the task(s) is incorrect. (Not sure why it's not giving an error.) The first positional argument always need to be the task name:
task(taskName, type: Exec) { ... }
In a build script, this will also work:
task "$taskName"(type: Exec) { ... }
I am using a Phing build script with Jenkins and would like to run it end to end on a job and capture all the reports. The problem is it stop building on a failed build step. Is there a way or a plugin that would continue the job even on failures?
Thanks
I don't know a lot about Phing but, since it's based on Ant, if the build step you are executing has a "failonerror" attribute you should be able to set it to false so that the entire build doesn't fail if the step returns an error.
Yes, use try, catch block in you pipeline scripts
example:
try {
// do some stuff that potentially fails
} catch (error) {
// do stuff if try fails
} finally {
// when you need some clean up to do
}
Or alternatively if you use sh commands to run these tests, consider running your sh scripts with the "|| true" suffix, this tells the linux sh script to exit with a result code of 0, even if your real command exited with an exit code.
example:
stage('Test') {
def testScript = ""
def testProjects = findFiles(glob: 'test/**/project.json')
if (!fileExists('reports/xml')) {
if (!fileExists('reports')) {
sh "mkdir reports"
}
sh "mkdir reports/xml"
}
for(prj in testProjects) {
println "Test project located, running tests: " + prj.path
def matcher = prj.path =~ 'test\\/(.+)\\/project.json'
testScript += "dotnet test --no-build '${prj.path}' -xml 'reports/xml/${matcher[0][1]}.Results.xml' || true\n"
}
sh testScript
