Gradle offline build does not work with Mac 10.9.3 - gradle

Question

I want to use my android studio 6.0 without internet connection, to do this, I set this options:
Preferences > Gradle > Offline work
but I am still get the message:
Gradle project sync failed. Basic functionality (e.g. editing,
debugging) will not work properly
When I try to compile, I get the Error:
Error running app: Gradle project sync failed. Please fix your project
and try again.
Could anyone help me or got the same problem?
Thank you

While I don't know what the exact problem is, I can suggest a workaround.
Change build.gradle to start with that:
buildscript {
repositories {
if ('allow' == System.properties['build.network_access']) {
mavenCentral()
} else {
maven {
url 'dependencies'
}
}
}
dependencies {
classpath 'com.android.tools.build:gradle:1.2.0-beta2'
}
}
apply plugin: 'com.android.application'
So, when build.network_access=allow gradle system property is defined, online mavenCentral() repository will be used. Otherwise, build will use local offline maven repository inside dependencies folder.
The trick now is to generate that local offline maven repository. For that I use this script (fetch_dependencies.py):
#!/usr/bin/python
import sys
import os
import subprocess
import glob
import shutil
# Place this in build.gradle:
# repositories {
# if ('allow' == System.properties['build.network_access']) {
# mavenCentral()
# } else {
# maven { url 'dependencies' }
# }
# }
def main(argv):
project_dir = os.path.dirname(os.path.realpath(__file__))
repo_dir = os.path.join(project_dir, "dependencies")
temp_home = os.path.join(project_dir, ".gradle_home")
if not os.path.isdir(temp_home):
os.makedirs(temp_home)
subprocess.call(["gradle", "-g", temp_home, "-Dbuild.network_access=allow"])
cache_files = os.path.join(temp_home, "caches/modules-*/files-*")
for cache_dir in glob.glob(cache_files):
for cache_group_id in os.listdir(cache_dir):
cache_group_dir = os.path.join(cache_dir, cache_group_id)
repo_group_dir = os.path.join(repo_dir, cache_group_id.replace('.', '/'))
for cache_artifact_id in os.listdir(cache_group_dir):
cache_artifact_dir = os.path.join(cache_group_dir, cache_artifact_id)
repo_artifact_dir = os.path.join(repo_group_dir, cache_artifact_id)
for cache_version_id in os.listdir(cache_artifact_dir):
cache_version_dir = os.path.join(cache_artifact_dir, cache_version_id)
repo_version_dir = os.path.join(repo_artifact_dir, cache_version_id)
if not os.path.isdir(repo_version_dir):
os.makedirs(repo_version_dir)
cache_items = os.path.join(cache_version_dir, "*/*")
for cache_item in glob.glob(cache_items):
cache_item_name = os.path.basename(cache_item)
repo_item_path = os.path.join(repo_version_dir, cache_item_name)
print "%s:%s:%s (%s)" % (cache_group_id, cache_artifact_id, cache_version_id, cache_item_name)
shutil.copyfile(cache_item, repo_item_path)
shutil.rmtree(temp_home)
return 0
if __name__ == "__main__":
sys.exit(main(sys.argv))
It will run the build in online mode to download all dependencies. After that, it will copy jars and poms into dependencies folder creating a local maven repository there. You can even push this dependencies folder into the source control.
After that you can build offline either with gradle --offline build (or just gradle build) or with Android Studio.
