`--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. [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` Refresh the state of resources of the type(s) specified. Currently only 'dependencies' is supported. [deprecated - Use '--refresh-dependencies' instead.]
`--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.
`-u, --no-search-upward` Don't search in parent folders for a settings.gradle file.

Build Setup
BUILD SUCCESSFUL in 2s- 列出所有task: gradle tasks
- 跳过单元测试: gradle build -x test
- 伪执行: 这种执行用在想要知道命令行中task的执行顺序，但又不真正执行task的时候，相当于“伪执行”。使用-m参数，如：gradle -m clean compile，将显示这个两个任务执行中涉及的任务，但又不会真正去执行它们。
- 使用自定义的Maven仓库 在build.gradle配置文件里加上
repositories {
maven { url "http://wjwtest:8081/nexus/content/groups/public" }
maven { url "http://repo.springsource.org/plugins-release" }
}- 初始化

AppTest.java- Maven项目秒变gradle项目
切换到你maven项目目录
然后执行:
gradle init --type pom你的maven项目已经秒变gradle项目
- Gradle 如何使用Maven本地缓存库（Local Maven repository） 从Maven切换到Gradle，原有的几G的本地缓存库当然想继续使用。
如果想使用Maven本地缓存，需要定义：
build.gradle文件下定义
repositories {
mavenLocal()
}Gradle使用与Maven相同的策略去定位本地Maven缓存的位置。如果在settings.xml中定义了本地Maven仓库的地址，则使用该地址。 在USER_HOME/.m2下的settings.xml文件中的配置会覆盖存放在M2_HOME/conf下的settings.xml文件中的配置。 如果没有settings.xml配置文件，Gradle会使用默认的USER_HOME/.m2/repository地址。
