无法从gradle解析com.google.guava。

Question

来自Netbeans的奇怪警告。

虽然我没有看到gradle本身的任何东西，至少到目前为止..:

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

我只运行了 git init 在一个基本为空的目录上，所以这更多的只是一种好奇心。

但我如何至少从gradle本身产生这个警告（这大概是IDE正在做的事情）？

我特意添加了 guava 按照说明，使本来是樱桃色的 建档 是。

 */

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()
}

我只是... 附加 maven central，还是会收到来自IDE的相同警告。

假设你的封装版本和你安装的版本一样。这个问题源于Netbeans不支持Gradle 6（参见 适用于netbeans的gradle插件).

最好的选择是简单地切换到Gradle 5（这是被支持的）。要做到这一点，你需要更新包装器的属性，从 gradle/wrapper/gradle-wrapper.properties.修改 distributionUrl 值，并将末端从 gradle-6.x-bin.zip 到其他版本，比如 gradle-5.2.1-bin.zip.

然后再运行一次构建，这样它就会下载包装器，再尝试NetBeans。

据我所知，你 build.gradle 在第5版中也应该可以使用，所以不需要修改。
