有没有简单的方法从本地gradle缓存中删除一个依赖项？

问题描述

本地gradle缓存存储maven / gradle依赖关系的副本。 涵盖了如何清除整个缓存，但不是单个包。

有没有简单的方法从本地gradle缓存中删除一个包？例如，在积极开发图书馆时，这会很有用。为了测试次要的库更改，我现在必须从文件系统清除整个高速缓存，以便不使用旧的高速缓存版本的库。

据我所知，也可以使用中描述的。我不希望更改gradle配置，因为大部分时间和大多数开发人员默认的缓存行为都很好。

解决方案

所以这里有一个快速的脚本：

seekanddestroy .gradle

  defaultTasks'seekAndDestroy'
 
 repositories {//此部分*需要*相同到你build.gradle的仓库部分
 jcenter（）
} 
 
配置{
 findanddelete 
} 
 
依赖关系{
 //添加您需要刷新的所有依赖项
 findanddelete'org.apache.commons：commons-math3：3.2'
} 
 
任务seekAndDestroy（）< ;< {
 configurations.findanddelete.each {
 println'删除：'+ it 
 delete it.parent 
} 
} 
  

您可以通过运行 gradle -b seekanddestroy.gradle

---

演示如何使用：
如果您的build.gradle如下所示：

  apply plugin：'java'
 
存储库{
 jcenter（）
} 
 
依赖关系{
 
 compile'org.apache.commons：commons-math3：3.2' 
} 
  

第一次构建时，包含一个下载依赖项：

 λgradle clean build | grep下载
下载https://jcenter.bintray.com/org/apache/commons/commons-math3/3.2/commons-math3-3.2.jar 
  

第二次清理构建，使用缓存的依赖关系，因此不需要下载：

 λgradle clean build | grep下载
  

现在执行seekanddestroy：

 λgradle -b seekanddestroy.gradle -q 
删除：.gradle \caches\modules-2\files-2.1\org.apache.commons\commons- math3 \3.2\ec2544ab27e110d2d431bdad7d538ed509b21e62\commons-math3-3.2.jar 
  

下一个构建，下载依赖再次：

 λgradle clean build | grep下载
下载https://jcenter.bintray.com/org/apache/commons/commons-math3/3.2/commons-math3-3.2.jar 
  

The local gradle cache stores copies of maven/gradle dependencies. How to clear gradle cache? covers how to clear the whole cache, but not individual packages.

Is there a simple way to remove one package from the local gradle cache? This would be useful, for example, when actively developing a library. To test a minor library change, I currently have to clear the entire cache from the filesystem so an old cached version of the library is not used.

I understand it is also possible to use the gradle ResolutionStrategy described in How can I force gradle to redownload dependencies?. I would prefer not to change the gradle configuration because most of the time and for most developers, the default caching behavior is fine.

解决方案

So here's a quick script I whipped up:

seekanddestroy.gradle

defaultTasks 'seekAndDestroy'

repositories{ //this section *needs* to be identical to the repositories section of your build.gradle
    jcenter()
}

configurations{
    findanddelete
}

dependencies{
    //add any dependencies that  you need refreshed
    findanddelete 'org.apache.commons:commons-math3:3.2'
}

task seekAndDestroy()<<{
    configurations.findanddelete.each{
        println 'Deleting: '+ it
        delete it.parent
    }
}

You can invoke this script by running gradle -b seekanddestroy.gradle

---

Demo of how it works:if your build.gradle looks like this:

apply plugin:'java'

repositories{
    jcenter()
}

dependencies{

    compile 'org.apache.commons:commons-math3:3.2'
}

First time build, includes a download of the dependency:

λ gradle clean build | grep Download
Download https://jcenter.bintray.com/org/apache/commons/commons-math3/3.2/commons-math3-3.2.jar

Second clean build, uses cached dependency, so no download:

λ gradle clean build | grep Download

Now run seekanddestroy:

λ gradle -b seekanddestroy.gradle  -q
Deleting: .gradle\caches\modules-2\files-2.1\org.apache.commons\commons-math3\3.2\ec2544ab27e110d2d431bdad7d538ed509b21e62\commons-math3-3.2.jar

Next build, downloads dependency again:

λ gradle clean build | grep Download
Download https://jcenter.bintray.com/org/apache/commons/commons-math3/3.2/commons-math3-3.2.jar
