使用Maven存储库进行Gradle离线构建

Question

I'm attempting to setup an offline Gradle build.

I would ideally like to have all my project dependencies in an arbitrary maven repository referenced as below:

repositories {
    maven {
        url 'file://PATH/TO/REPO'
    }
}

However, the above fails in a fresh Gradle install (no ~/.gradle cache) with the following:

* What went wrong
Plugin [id: PLUGINID, version: PLUGINVERSION] was not found in any of the 
following sources:

- Gradle Core Plugins (plugin is not in 'org.gradle' namespace)
- Plugin Repositories (could not resolvee plugin artifact     'PLUGINID:PLUGINNAME:PLUGINVERSION')
    Searched in the following repositories: 
        Gradle Central Plugin Repository 

I've tried a few different ways to specify the repository, including:

1. Replacing "url..." with "flatDir { dir '/PATH/TO/REPO' }".
2. Copying all dependencies to ~/.m2 and calling mavenLocal() as the repository.

To copy dependencies from ~/.gradle/caches/modules-2/files-2.1/ into my "offline" repository, I have tried:

1. Straight copy/paste

2. A Gradle task which converts the structure as such:

    task cacheLocal(type: Copy) { from new File(gradle.gradleUserHomeDir, 'caches/modules-2/files-2.1') into '/PATH/TO/REPO' eachFile { List<String> parts = it.path.split('/') it.path = (parts[0] + '/' + parts[1]).replace('.','/') + '/' + parts[2] + '/' + parts[4] } includeEmptyDirs = false } 

Other things:

• Running with "--offline" makes no difference.
• Build is successful if ~/.gradle is already present, but fails otherwise.

My plugins block (the above error statement will hit the first non-Gradle core plugin, so protobuf in this case):

plugins {
    id "com.google.protobuf" version "0.8.6"
    id "nebula.ospackage" version "4.9.3"
    id "java"
    id "eclipse"
}

This is out of my depth and any help would be greatly appreciated!

Answer 1

If you want also plugins to be resolved from a local repository, you have to configure the pluginManagement section to do so. In your question, it looks like you only configured project repositories.

See the example in the documentation
