I recently installed wpilib on my windows laptop and start an project, but when I try to build the project using gradlew
it doesnt work:
Here is my build.gradle
:
plugins {
id "java"
id "edu.wpi.first.GradleRIO" version "2024.1.1"
}
java {
sourceCompatibility = JavaVersion.VERSION_17
targetCompatibility = JavaVersion.VERSION_17
}
def ROBOT_MAIN_CLASS = "frc.robot.Main"
// Define my targets (RoboRIO) and artifacts (deployable files)
// This is added by GradleRIO's backing project DeployUtils.
deploy {
targets {
roborio(getTargetTypeClass('RoboRIO')) {
// Team number is loaded either from the .wpilib/wpilib_preferences.json
// or from command line. If not found an exception will be thrown.
// You can use getTeamOrDefault(team) instead of getTeamNumber if you
// want to store a team number in this file.
team = project.frc.getTeamNumber()
debug = project.frc.getDebugOrDefault(false)
artifacts {
// First part is artifact name, 2nd is artifact type
// getTargetTypeClass is a shortcut to get the class type using a string
frcJava(getArtifactTypeClass('FRCJavaArtifact')) {
}
// Static files artifact
frcStaticFileDeploy(getArtifactTypeClass('FileTreeArtifact')) {
files = project.fileTree('src/main/deploy')
directory = '/home/lvuser/deploy'
}
}
}
}
}
def deployArtifact = deploy.targets.roborio.artifacts.frcJava
// Set to true to use debug for JNI.
wpi.java.debugJni = false
// Set this to true to enable desktop support.
def includeDesktopSupport = false
// Defining my dependencies. In this case, WPILib (+ friends), and vendor libraries.
// Also defines JUnit 5.
dependencies {
implementation wpi.java.deps.wpilib()
implementation wpi.java.vendor.java()
roborioDebug wpi.java.deps.wpilibJniDebug(wpi.platforms.roborio)
roborioDebug wpi.java.vendor.jniDebug(wpi.platforms.roborio)
roborioRelease wpi.java.deps.wpilibJniRelease(wpi.platforms.roborio)
roborioRelease wpi.java.vendor.jniRelease(wpi.platforms.roborio)
nativeDebug wpi.java.deps.wpilibJniDebug(wpi.platforms.desktop)
nativeDebug wpi.java.vendor.jniDebug(wpi.platforms.desktop)
simulationDebug wpi.sim.enableDebug()
nativeRelease wpi.java.deps.wpilibJniRelease(wpi.platforms.desktop)
nativeRelease wpi.java.vendor.jniRelease(wpi.platforms.desktop)
simulationRelease wpi.sim.enableRelease()
testImplementation 'org.junit.jupiter:junit-jupiter:5.10.1'
testRuntimeOnly 'org.junit.platform:junit-platform-launcher'
}
test {
useJUnitPlatform()
systemProperty 'junit.jupiter.extensions.autodetection.enabled', 'true'
}
// Simulation configuration (e.g. environment variables).
wpi.sim.addGui().defaultEnabled = true
wpi.sim.addDriverstation()
// Setting up my Jar File. In this case, adding all libraries into the main jar ('fat jar')
// in order to make them all available at runtime. Also adding the manifest so WPILib
// knows where to look for our Robot Class.
jar {
from { configurations.runtimeClasspath.collect { it.isDirectory() ? it : zipTree(it) } }
from sourceSets.main.allSource
manifest edu.wpi.first.gradlerio.GradleRIOPlugin.javaManifest(ROBOT_MAIN_CLASS)
duplicatesStrategy = DuplicatesStrategy.INCLUDE
}
// Configure jar and deploy tasks
deployArtifact.jarTask = jar
wpi.java.configureExecutableTasks(jar)
wpi.java.configureTestTasks(test)
// Configure string concat to always inline compile
tasks.withType(JavaCompile) {
options.compilerArgs.add '-XDstringConcat=inline'
}
Now if I build with gradle, it builds perfectly fine
settings.gradle:
import org.gradle.internal.os.OperatingSystem
pluginManagement {
repositories {
mavenLocal()
gradlePluginPortal()
String frcYear = '2024'
File frcHome
if (OperatingSystem.current().isWindows()) {
String publicFolder = System.getenv('PUBLIC')
if (publicFolder == null) {
publicFolder = "C:\\Users\\Public"
}
def homeRoot = new File(publicFolder, "wpilib")
frcHome = new File(homeRoot, frcYear)
} else {
def userFolder = System.getProperty("user.home")
def homeRoot = new File(userFolder, "wpilib")
frcHome = new File(homeRoot, frcYear)
}
def frcHomeMaven = new File(frcHome, 'maven')
maven {
name 'frcHome'
url frcHomeMaven
}
}
}
Properties props = System.getProperties();
props.setProperty("org.gradle.internal.native.headers.unresolved.dependencies.ignore", "true");
I expected that it would build with gradlew as well but it doesnt,
heres my gradle-wrapper.properties
distributionBase=GRADLE_USER_HOME
distributionPath=permwrapper/dists
distributionUrl=https\://services.gradle.org/distributions/gradle-8.5-bin.zip
networkTimeout=10000
validateDistributionUrl=true
zipStoreBase=GRADLE_USER_HOME
zipStorePath=permwrapper/dists
instead of building it gives me this:
>gradlew
Exception in thread "main" java.lang.ClassNotFoundException: org.gradle.launcher.GradleMain
at java.base/java.net.URLClassLoader.findClass(URLClassLoader.java:445)
at java.base/java.lang.ClassLoader.loadClass(ClassLoader.java:593)
at java.base/java.lang.ClassLoader.loadClass(ClassLoader.java:526)
at org.gradle.wrapper.GradleWrapperMain.main(SourceFile:70)
I have even tried regenerating the wrapper, gradle wrapper
ALSO: FOR SOME REASON gradlew
doesnt listen to commands its only building no matter what
EDIT: I have tried my code on github codespaces and my own linux (arch linux) but windows isn't working for me, i have reinstalled wpilib multiple times not sure why its doing this to me. I have tried using a vm of windows and it works it weird why my computer doesn't work.
The solution to this error was that you had to remove .gradle
folder in your home directory C:\Users\{username}\
. Now something must happened during my installation that caused this error to happen. Everything builds correctly now.
NOTE: You have to reboot your computer before removing it because it won't let you remove unless you reboot.
