curl -s https://raw.githubusercontent.com/oscm/shell/38c2d4d307ce7a0760fc88d5d9703eef64d3b81c/lang/java/gradle/gradle-2.9.sh | bash
安装后运行 gradle --help 验证释放正确安装。
# gradle --help 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.
