无法从 gradle 解析 com.google.guava

Question

来自 Netbeans 的奇怪警告：

尽管我从 gradle 本身看不到任何东西，至少到目前为止：

thufir@dur:~/NetBeansProjects/expectit$ 
thufir@dur:~/NetBeansProjects/expectit$ gradle clean

我只运行 git init 在一个基本上是空的目录上，所以它只是一种好奇心。

但是我如何至少从 gradle 本身生成此警告（这大概是 IDE 正在做的事情）？

我根据说明添加了 guava，因此 cherry build file 是：

/*
 * This file was generated by the Gradle 'init' task.
 *
 * This generated file contains a sample Java project to get you started.
 * For more details take a look at the Java Quickstart chapter in the Gradle
 * User Manual available at https://docs.gradle.org/6.3/userguide/tutorial_java_projects.html
 */

plugins {
    // Apply the java plugin to add support for Java
    id 'java'

    // Apply the application plugin to add support for building a CLI application.
    id 'application'
}

repositories {
    // Use jcenter for resolving dependencies.
    // You can declare any Maven/Ivy/file repository here.
    jcenter()
    mavenCentral()
}

dependencies {
    // This dependency is used by the application.
    implementation 'com.google.guava:guava:28.2-jre'

    // Use TestNG framework, also requires calling test.useTestNG() below
    testImplementation 'org.testng:testng:7.0.0'
}

application {
    // Define the main class for the application.
    mainClassName = 'expectit.App'
}

test {
    // Use TestNG for unit tests
    useTestNG()
}

我只added maven central 如上；仍然从 IDE.

得到相同的警告

Answer 1

假设您的包装器版本与您安装的版本相同。问题源于 Netbeans 不支持 Gradle 6（参见 gradle plugin for netbeans）。

最好的选择就是切换到 Gradle 5（支持）。为此，您需要从 gradle/wrapper/gradle-wrapper.properties 更新包装器属性。修改 distributionUrl 值，并将结尾从 gradle-6.x-bin.zip 更改为其他版本，例如 gradle-5.2.1-bin.zip.

然后运行再次构建，以便下载包装器并再次尝试 NetBeans。

据我所知，build.gradle 应该也适用于版本 5，因此无需修改它。
