WPILIB (FRC) Gradlew 问题（Gradle 构建正常，但 gradlew 不行）

Question

我最近在我的 Windows 笔记本电脑上安装了 wpilib 并启动了一个项目，但是当我尝试使用

gradlew

构建项目时，它不起作用：

这是我的

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'
}

现在如果我用 gradle 构建，它构建得非常好

设置.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");

我预计它也会用 gradlew 构建，但事实并非如此，

这是我的 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

它没有构建它而是给了我这个：

>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)

我什至尝试过重新生成包装纸，

gradle wrapper

还：出于某种原因

gradlew

不听命令，无论如何，它是唯一的建筑

编辑： 我已经在 github codespaces 和我自己的 linux (arch linux) 上尝试了我的代码，但是 windows 不适合我，我已经重新安装了 wpilib 多次，不知道为什么它对我这样做。我尝试过使用 Windows 虚拟机，但它的工作原理很奇怪，为什么我的计算机无法工作。

此错误的解决方案是您必须删除主目录中的

.gradle

文件夹

C:\Users\{username}\

。现在，在我的安装过程中一定发生了一些导致此错误发生的事情。现在一切都正确构建了。

注意：在删除之前您必须重新启动计算机，因为除非您重新启动，否则它不会让您删除。
