之前公司有一个旧的Jenkins在提供客户端打包，随着时间的推移发现默认gradle占用根分区的资源空间越来越大。照成数据盘有很大闲置，而根分区不够的现象。
可以看到我根分区剩余空间非常少
经过排查发现gradle 的默认目录占的比较大，为了合理运用资源，就想着移动gradle的默认目录
网上也找了好多。什么5中方式改变gradl的目录。发现好多都是windows的。其中发现了一个但用处不是很大。
最后通过
[root@dbjenkins gradle_cache]# gradle --h
USAGE: gradle [option...] [task...]
-?, -h, --help Shows this help message.
-a, --no-rebuild Do not rebuild project dependencies.
-b, --build-file Specifies the build file.
-c, --settings-file Specifies the settings file.
--configure-on-demand Only relevant projects are configured in this build run. This means faster build for large multi-project builds. [incubating]
--console Specifies which type of console output to generate. Values are ‘plain‘, ‘auto‘ (default) or ‘rich‘.
--continue Continues task execution after a task failure.
-D, --system-prop Set system property of the JVM (e.g. -Dmyprop=myvalue).
-d, --debug Log in debug mode (includes normal stacktrace).
--daemon Uses the Gradle daemon to run the build. Starts the daemon if not running.
--foreground Starts the Gradle daemon in the foreground. [incubating]
-g, --gradle-user-home Specifies the gradle user home directory.
--gui Launches the Gradle GUI.
-I, --init-script Specifies an initialization script.
-i, --info Set log level to info.
-m, --dry-run Runs the builds with all task actions disabled.
--max-workers Configure the number of concurrent workers Gradle is allowed to use. [incubating]
--no-color Do not use color in the console output. [deprecated - use --console=plain instead]
--no-daemon Do not use the Gradle daemon to run the build.
--offline The build should operate without accessing network resources.
-P, --project-prop Set project property for the build script (e.g. -Pmyprop=myvalue).
-p, --project-dir Specifies the start directory for Gradle. Defaults to current directory.
--parallel Build projects in parallel. Gradle will attempt to determine the optimal number of executor threads to use. [incubating]
--parallel-threads Build projects in parallel, using the specified number of executor threads. [deprecated - Please use --parallel, optionally in conjunction with --max-workers.] [incubating]
--profile Profiles build execution time and generates a report in the <build_dir>/reports/profile directory.
--project-cache-dir Specifies the project-specific cache directory. Defaults to .gradle in the root project directory.
-q, --quiet Log errors only.
--recompile-scripts Force build script recompiling.
--refresh-dependencies Refresh the state of dependencies.
--rerun-tasks Ignore previously cached task results.
-S, --full-stacktrace Print out the full (very verbose) stacktrace for all exceptions.
-s, --stacktrace Print out the stacktrace for all exceptions.
--stop Stops the Gradle daemon if it is running.
-t, --continuous Enables continuous build. Gradle does not exit and will re-execute tasks when task file inputs change. [incubating]
-u, --no-search-upward Don‘t search in parent folders for a settings.gradle file.
-v, --version Print version info.
-x, --exclude-task Specify a task to be excluded from execution.发现
-g，--gradle-user-home指定gradle用户的主目录。
--project-cache-dir指定特定于项目的缓存目录。在根项目目录中默认为.gradle。
[root@dbjenkins ~]# mkdir /dbox/gradle_cache/
建立gradle 的主目录，和缓存目录
[root@dbjenkins gradle_cache]# gradle -g /dbox/gradle_cache
:help
Welcome to Gradle 2.14.1.
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: 1.662 secs
This build could be faster, please consider using the Gradle Daemon: https://docs.gradle.org/2.14.1/userguide/gradle_daemon.html我是把缓存目录和主目录放在一起了，方便以后查找

发现目录下已经生成了一些默认的目录
