如何从命令行更新 Gradle 依赖项？

Question

I have following build.gradle file:

apply plugin: 'java'
apply plugin: 'eclipse'

sourceCompatibility = 1.7
version = '1.0'

repositories {
    mavenCentral()
}

dependencies {
    compile 'org.springframework:spring-core:4.1.1.RELEASE'
    compile 'org.springframework:spring-context:4.1.1.RELEASE'
    testCompile group: 'junit', name: 'junit', version: '4.+'
}

I run following command:

$ gradle --refresh-dependencies

But it does nothing. The dependencies do not get updated and do not reflect on classpath. The output from command is:

:help

Welcome to Gradle 2.1.

To run a build, run gradle <task> ...

To see a list of available tasks, run gradle tasks

To see a list of command-line options, run gradle --help

BUILD SUCCESSFUL

Total time: 5.999 secs

Doing this via Eclipse gradle plugin is working though.

Answer 1

gradle --refresh-dependencies <task>

Answer 2

我使用的是 Gradle 2.9，我用它来强制刷新：

gradle build --refresh-dependencies

Answer 3

您应该首先使用gradle clean ，然后gradle eclipse最后转到 eclipse 中的项目并刷新项目，它适用于我的。

Answer 4

for gradle refresh to perform , run the below command via command prompt

gradle --refresh-dependencies clean build

Answer 5

If you want to fetch dependencies without running build (or all the tasks), you could use dependency-verification :

gradle --write-verification-metadata sha256 help

Note that as explained here :

it's an approximation of what dependencies could be downloaded during a build. In particular, if a task uses what we call a “detached configuration” (a dynamic dependency graph at execution time), then those dependencies will not be downloaded, because they are opaque to Gradle.

Answer 6

If you have multiple projects then and want to execute only on one project the clean-eclipse (without quotation marks)

gradle 'project name':clean 'project name':eclipse --refresh-dependencies

after you just refresh the project in your IDE.
