I have a problem with allure reports. When I run command ./gradlew allureReport after tests execution I've got an empty report with text like 'Allure Report unknown NaN%'. Does anyone have the same problem?
Here is my build.gradle configuration file:
buildscript {
repositories {
jcenter()
}
dependencies {
classpath "io.qameta.allure:allure-gradle:2.8.1"
}
}
plugins {

}
apply plugin: 'io.qameta.allure'
allure {

reportDir = file('build/allure-results')
}

You have not added the allure-maven dependency under your dependencies section.I think that's why you are getting this NaN% error.
It seems that there are spaces in one of the parent folder names. So, if there are spaces in folder name, keep the folder name in double quotes. Refer to the example below:
Run Allure command(allure serve) by keeping folder name in double quotes.
Suppose folder name is test automation
Incorrect: allure serve D:\test automation\webautomation\allure-results
Correct: allure serve D:\"test automation"\webautomation\allure-results
I also faced the same issue and you have to specify the path within the double quotes in the command prompt if there are any white spaces between the folder names.
For example, if your allure results are in the following folder - D:\test automation\webautomation\allure-results, you have to specify the command as below.
allure serve "D:\test automation\webautomation\allure-results"

I tried to use the Springframework WebClient (I use IntelliJ with gradle), and in the "dependencies" section of the build.gradle, I added
“compile group: ‘org.springframework.boot’, name: ‘spring-boot-starter-webflux’, version: versions.spring_boot”
However, when I do gradle build, it failed in the lintGradle task with the following errors:

Not sure if I need to add something else to the gradle build setting environment? Or if the webflux dependency conflicts with other dependencies?
There is a parent folder Par and child folder Child, they both have their build.gradle respectively. The build task in the Child folder passed but failed in the Par folder with the errors above.

Thank you
If you are using Spring MVC and the new WebClient from Spring WebFlux in the same application, Spring MVC will be used by default. You can override that easily by calling setWebApplicationType(WebApplicationType).
It will be helpful if you can share build.gradle.
Problem: I have a gradle project in which I am using let's say 'pocdemo.jar' as gradle dependency. When I try to navigate through the method call hierarchy, it doesn't show the actual code, instead it shows something like shown in image below
I want to have the source attached for the external dependency, I tried to do that by selecting the jar -> properties -> Java Source Attachment, but that didn't allow me to add the location for the source. Now I want to know is there a way that I can use in build.gradle file that will include the source during the jar creation itself.
I have the below gradle file for the project that I use as external dependency in my main project.

I have the same issue too when using Spring Tool Suite, and I spent a lot of time investigating but cannot find any solutions.
But when I use Intellij, it works fine, I can go into the class file and debug it. So please try it with Intellij.

Right now i use "gradlew test" to run my tests from jenkins.
I want to give input from jenkins to run only CLAs.xml file. Like this i have many XML files avaliable . I want to parameterize the job to pick only required testng files and run.
Can someone help me how to setup this test task in build.gradle file and jenkins
Thanks in advance
Modify the useTestNG() in your build.grade . It should accept one dynamic parameter e.g. xmlName.
test {
useTestNG()
{
suites "src/test/resources/ACE_Regression/${xmlName}.xml"
}
}
Pass the xmlName using -P option in your gradle invocation block. i.e. gradlew test -PxmlName=CLAs , it should work.
To make it more dynamic, Make your jenkins build parameterized. Create a choice parameter by the name of testSuites and add all the possible xml file names in it.
Then pass this choice parameter to the gradle invocation command block i.e. gradle test -PxmlName=${testSuites}
Edit: This question is a duplicate to this question, which got incorrectly marked as duplicate, forcing me to restate my question.
To preface this, yes, I have seen this thread, but it did not help me. Specificly, while multiple people mentioned that different class structures between the building branch and the environment branch can exists, noone said anything about how to test for that, let alone fix it. And even then, I am not certain that this is really root cause.
I am working on a gradle project and I wanted to compile the project I had, to test it outside of my IDE, Netbeans 8.2, in which it works fine.
When I try to run the program with the usual java -jar command, it initally works fine, until the programs comes across a class that can throw a JDOMException. Then I get the error described in the title, followed by a NoClassDefFoundError.
In Netbeans, the JDOMException.class is included under Dependencies>Compile for main>jdom2-2.0.6.jar>org.jdom2
And the build.gradle script reads:
apply plugin: 'java'
sourceCompatibility = 1.8

)
}
}
I am using java jdk 1.8.0_202 in Netbeans and jre 1.8.0_211-b12 as runtime environment. I have found answers along the lines of "You have to add jdom2 to your runtime environment", however I neither know how to do that, nor if that is a general solution to the problem.
I'd appreciate the help!
The problem was that, by default, gradle does not include external dependencies when building a normal .jar file. I had to instruct gradle to build a "fat jar" file instead.
I did this by altering the
jar {
...
}
part of my gradle script into the following instruction:
jar {
manifest {
attributes(
'Main-Class': 'bikesys.hda.BikeSys'
)
}
from {
configurations.compileClasspath.filter{ it.exists() }.collect { it.isDirectory() ? it : zipTree(it) }
}
}
Be sure to edit the class path, which in my case was bikesys.hda.BikeSys, to your main class.

I know I'm not going to be needing at least 7 out of those 10 hadoop dependencies, but I don't know which of these dependencies have org.apache.hadoop.mapreduce package (I know these 11 don't though).
Which dependency/repository should I add so that I can actually build a mapreduce job?
Can I do that with raw org.apache.hadoop packages and not vendor packages (such as Cloudera)?
Thanks in advance for all the help.
This should be the correct dependency:
compile 'org.apache.hadoop:hadoop-mapreduce-client-core:2.7.3'
Be sure to refresh your gradle project.
Add
compile group: 'org.apache.hadoop', name:'hadoop-core', version: '2.7.3'
For newer versions of Gradle (I'm using 7.5.1) compile isn't an option anymore. In that case, you should use implementation.
dependencies {
implementation 'org.apache.hadoop:hadoop-common:2.7.7'
implementation 'org.apache.hadoop:hadoop-mapreduce-client-core:2.7.7'
}
