Gradle store on local file system

问题:

How does Gradle store downloaded jar files on the local file system? Maven stores them in the .m2 directory under USER_HOME, but where does Gradle store them? I checked the .gradle folder there, but saw only compiled scripts.

回答1:

Gradle caches artifacts in USER_HOME/.gradle folder. The compiled scripts are usually in the .gradle folder in your project folder.

If you can't find the cache, maybe it's because you have not cached any artifacts yet. You can always see where Gradle has cached artifacts with a simple script:

apply plugin: 'java'

repositories{
  mavenCentral()
}

dependencies{
  compile 'com.google.guava:guava:12.0'
}

task showMeCache << {
  configurations.compile.each { println it }
}

Now if you run gradle showMeCache it should download the deps into cache and print the full path.

On Mac, Linux and Windows i.e. on all 3 of the major platforms, Gradle stores dependencies at:

~/.gradle/caches/modules-2/files-2.1

回答3:

If you want your dependency files to be in some specific folder you can simply use a copy task for it. For Eg.

task copyDepJars(type: Copy) {
  from configurations.compile
  into 'C:\\Users\\athakur\\Desktop\\lib'
}

In Windows 10 PC, it is saved at:

C:\Users\<user>\.gradle\caches\modules-2\files-2.1\

回答5:

I am on windows,

You should be able find the dependencies inside

$USER_HOME.gradle\caches\artifacts-24\filestore

回答6:

Gradle's local repository folder is:

• $USER_HOME/.gradle/caches/modules-2/files-2.1

Defined dependencies will be loaded from remote repositories into gradle's local repository folder. For each loaded file, gradle will be create a new folder named with md5 value of the original file (pom,jar,..). Full path for the dependency file is made up from :

• groupid + artifactid + version + FILE_MD5_VALUE + FILE_NAME

If our defined dependency is:

• compile 'org.springframework:spring-jdbc:4.3.4.RELEASE'

Then the library will be loaded into :

• /$USER_HOME/.gradle/caches/modules-2/files-2.1/org.springframework/spring-jdbc/4.3.4.RELEASE/42175d194cf6aa7c716c0887f30255e5c0a5262c/spring-jdbc-4.3.4.RELEASE.jar

回答7:

You can use the gradle argument --project-cache-dir "/Users/whatever/.gradle/" to force the gradle cache directory.

In this way you can be darn sure you know what directory is being used (as well as create different caches for different projects)

回答8:

It took me a while to realize this, hence the additional answer. Hopefully it can save folks time. Note that if you are running sudo gradle the dependencies may not be in your home directory, even if sudo echo $HOME returns /Users/<my-non-root-user>/. On my Mac, Gradle was caching the dependencies in /private/var/root/.gradle/caches/.

回答9:

In case it is an Android gradle project - you can find the android libraries below your $ANDROID_HOME/extras/android/m2repository folder

回答10:

In android studio do the following steps to check the gradle downloaded jar file.

1. Set project structure view to "Project"
2. At bottom External library section available, expand it.
3. Here you can see downloaded jar files.

回答11:

On my windows machine with "Buildship 2.0.2" plugin installed in eclipse, dependencies are stored :

$USER_HOME.gradle\caches\modules-2\files-2.1

回答12:

For my case, I was using an Ivy repository, and my Gradle dependencies were stored in ~/.ivy2/.

回答13:

I just stumbled onto this while searching for this answer. If you are using intellij, you can navigate to the file location, but opening the external lib folder in the project explorer, right clicking on the jar, and select Open Library Settings.

回答14:

In fact the cache location depends on the GRADLE_USER_HOME environment variable value. By default, it is $USER_HOME/.gradle on Unix-OS based and %userprofile%.\gradle on Windows.
But if you set this variable, the cache directory would be located from this path.

And whatever the case, you should dig into caches\modules-2\files-2.1 to find the dependencies.
