Gradle checkstyle plugin xml report - gradle

as i know checkstyle creates two types of report, xml and plain text. Which parameter i should update to make report as xml?
example xml output
java com.puppycrawl.tools.checkstyle.Main -c docs/sun_checks.xml \
-f xml -o build/checkstyle_errors.xml Check.java

Ok, answer found, create reportsDir property in checkstyle.
example
checkstyle {
toolVersion = '6.4'
configFile = file('google_checks.xml');
reportsDir = file("$project.buildDir/reports/checkstyle/")
}

How to add multiple tasks of the same type in Gradle?

I need to generate FlatBuffers files from *.fbs file before the build.
So i'm using gradle.plugin.io.netifi:gradle-flatbuffers-plugin:1.0.7 to do it for me.
It works as expected for 1 task:
def generatedSourcePathJava = "$buildDir/generated/source/flatbuffers/java"
def generatedSourcePathCpp = "$buildDir/generated/source/flatbuffers/cpp"
...
task createFlatBuffersJava(type: io.netifi.flatbuffers.plugin.tasks.FlatBuffers) {
outputDir = file(generatedSourcePathJava)
language = "kotlin"
}
build.dependsOn createFlatBuffersJava
But if i add the 2nd one (to generate C++ files for JNI):
task createFlatBuffersJava(type: io.netifi.flatbuffers.plugin.tasks.FlatBuffers) {
outputDir = file(generatedSourcePathJava)
language = "kotlin"
}
task createFlatBuffersCpp(type: io.netifi.flatbuffers.plugin.tasks.FlatBuffers) {
outputDir = file(generatedSourcePathCpp)
language = "cpp"
}
assemble.dependsOn createFlatBuffersJava, createFlatBuffersCpp
Gradle build (../gradlew :engine-flatbuffers:clean :engine-flatbuffers:build) fails with the following:
What went wrong:
A problem occurred configuring project ':engine-flatbuffers'.
java.util.ConcurrentModificationException (no error message)
I think the question can be generalized to "How to add multiple tasks of the same type in Gradle?".
PS. "gradle-5.6-all"
That's a known plugin bug/feature reported at https://github.com/gregwhitaker/gradle-flatbuffers-plugin/issues/7.
It works in 1.0.5 but kotlin [argument] is sadly not supported there at that point. java works and it's compatible.

Antlr4 - generate grammar source for more language in gradle

In my project I have to generate the grammar sources for more than one language (Java, Javascript and Python) using gradle.
I'm using the antlr plugin, so I have the following rows in my build.gradle file:
apply plugin: 'antlr'
generateGrammarSource {
def languageFlag = project.hasProperty('Language') ?project.property('Language') : 'Python2'
arguments = ['-Dlanguage=' + languageFlag]
def pythonOutputDirectory = "python/engine_lib/kpi_attributes"
switch (languageFlag) {
case "Java":
outputDirectory = file("../../../../XSpotterGUI/sviluppo/src/com/xech/xspotter4/grammars/kpiattributes")
arguments += ['-package', 'com.xech.xspotter4.grammars.kpiattributes']
break
case "JavaScript":
outputDirectory = file("../../../../XSpotterGUI/sviluppo/WebContent/xspotter4/js/xech/grammars/kpiattributes")
break
case "Python2":
outputDirectory = file(pythonOutputDirectory)
break
}
description = 'Generates Java sources from Antlr4 grammars.'
maxHeapSize = "64m"
sourceSets.main.antlr.srcDirs = ['.']
includes = ['KpiAttributes.g4']
doLast {
if (languageFlag.equals("Python2")) {
File file = new File("$pythonOutputDirectory/__init__.py")
file.write ""
}
}
}
I omitted the rows regarding repositories, dependencies and so on.
In this way I'm able to call gradle three times:
./gradlew generateGrammarSource -PLanguage=Java
./gradlew generateGrammarSource -PLanguage=Python2
./gradlew generateGrammarSource -PLanguage=JavaScript
But I have not been able to create a task 'generateAllGrammarSources' in order to call gradlew only ONE time and generate all sources

jenkinsfile - How do I access custom properties in my pom.xml?

Let's say I have a custom property in my pom.xml set like this:
<properties>
<app>com.myProject.app</app>
</properties>
How can I access it in my jenkinsfile?
This:
def pom = readMavenPom file: 'pom.xml'
def appName = pom.app
returns
org.jenkinsci.plugins.scriptsecurity.sandbox.RejectedAccessException: unclassified field org.apache.maven.model.Model app
Thanks in advance!
I know two approaches:
Use properties-maven-plugin to write the properties to a file. Use readProperties in the Jenkinsfile to read the properties.
Works only if properties aren't needed until after Maven ran.
Also, with the right circumstances, the properties file may be the stale one from a previous run, which is insiduous because the property values will be right anyway 99.9% of the time.
Use pom = readMavenPom 'path/to/pom.xml'. Afterwards, access the property like this: pom.properties['com.myProject.app'].
I like approach 2 much better: No extra plugin configuration in the POM, no file written, less sequencing constraints, less fragilities.
In pipeline style, inside Jenkinsfile you can access the value as follows
pipeline {
environment {
POM_APP = readMavenPom().getProperties().getProperty('app')
}
stages{
stage('app stage'){
steps{
script{
sh """
echo ${POM_APP}
"""
}
}
}
}
Read a maven project file
try this:
IMAGE = readMavenPom().getArtifactId()
VERSION = readMavenPom().getVersion()
jenkins pipeline add this stage.
more see
stage('info')
{
steps
{
script
{
def version = sh script: 'mvn help:evaluate -Dexpression=project.version -q -DforceStdout', returnStdout: true
def artifactId = sh script: 'mvn help:evaluate -Dexpression=project.artifactId -q -DforceStdout', returnStdout: true
}
}
}

Is it possible to override gradle from prompting error because ("." and "-") in the name of a variable? eg; name.dir (.dir not found) in task

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.

Passing “-J-Duser.language” to gradle not working

I want to have English messages when compiling.
Following this post and this, I added the following to my build.gradle
compileJava {
options.compilerArgs << '-J-Duser.language=en'
options.fork = true
options.forkOptions.executable = 'javac'
}
But I get ([] is my translation, not official)
javac: 无效的标记[invalid flags]: -J-Duser.language=en
用法[usage]: javac <options> <source files>
-help 用于列出可能的选项[for possible options]
In cmd, a simple javac -J-Duser.language=en do gives me English messages.
My question:
What am I doing wrong?
How can I make gradle show the exact javac command used when compiling?
Instead of using -J, passing the flag to options.forkOptions.jvmArgs should work:
tasks.withType(JavaCompile) {
options.fork = true
options.forkOptions.jvmArgs += ["-Duser.language=en"]
}
