Gradle 构建不下载依赖项

Question

在我的 Web 应用程序的根目录中运行 gradle build 后，在 build.gradle 中声明的 spring security 依赖项没有被下载。

这是我的 build.gradle

 /*
 * This build file was auto generated by running the Gradle 'init' task
 * by 'hombod' at '7/19/16 4:19 PM' with Gradle 2.14.1
 *
 * This generated file contains a commented-out sample Java project to get you started.
 * For more details take a look at the Java Quickstart chapter in the Gradle
 * user guide available at https://docs.gradle.org/2.14.1/userguide/tutorial_java_projects.html
 */

// Apply the java plugin to add support for Java
apply plugin: 'java'

// In this section you declare where to find the dependencies of your project
repositories {
    // Use 'jcenter' for resolving your dependencies.
    // You can declare any Maven/Ivy/file repository here.
    jcenter()
    mavenCentral()
}

// In this section you declare the dependencies for your production and test code
dependencies {
    // The production code uses the SLF4J logging API at compile time
    compile 'org.slf4j:slf4j-api:1.7.21'

    // Declare the dependency for your favourite test framework you want to use in your tests.
    // TestNG is also supported by the Gradle Test task. Just change the
    // testCompile dependency to testCompile 'org.testng:testng:6.8.1' and add
    // 'test.useTestNG()' to your build script.
    testCompile 'junit:junit:4.12'

    compile 'org.springframework.security:spring-security-web:4.1.1.RELEASE'
}

相反，我只是收到这条消息

:compileJava UP-TO-DAT
:processResources UP-T
:classes UP-TO-DATE
:jar UP-TO-DATE
:assemble UP-TO-DATE
:compileTestJava UP-TO
:processTestResources
:testClasses UP-TO-DAT
:test UP-TO-DATE
:check UP-TO-DATE
:build UP-TO-DATE

这是我运行 gradle init 命令的 spring mvc web 应用程序

Answer 1

系统缓存依赖的 jar，这样它就不会被一次又一次地下载。

如果您的目标只是查看依赖项的下载，那么您可以强制它重新下载。

删除本地存储的任何依赖项缓存 [1]

 $ rm -rf ~/.gradle/caches/

然后重新启动你的构建

$ gradlew clean build

您还可以使用 [2] 强制更新依赖项

$ gradlew --refresh-dependencies
