tapas コマンド

Building

Trade Federation is set up in a lightweight "unbundled" branch that uses slightly different build commands from the platform source. In particular, unbundled branches use the tapas command to set up the build environment, rather than the lunch command. So starting from the root directory of the source tree you checked out, try:

$ . build/envsetup.sh
$ tapas tradefed-all
$ m -j8
Note that once the $ . build/envsetup.sh step is done, the other two commands will run equally well from anywhere in the tree.

aosp build/envsetup.shのコマンド

Invoke ". build/envsetup.sh" from your shell to add the following functions to your environment:
- lunch:     lunch <product_name>-<build_variant>
- tapas:     tapas [<App1> <App2> ...] [arm|x86|mips|armv5|arm64|x86_64|mips64] [eng|userdebug|user]
- croot:     Changes directory to the top of the tree.
- m:         Makes from the top of the tree.
- mm:        Builds all of the modules in the current directory, but not their dependencies.
- mmm:       Builds all of the modules in the supplied directories, but not their dependencies.
             To limit the modules being built use the syntax: mmm dir/:target1,target2.
- mma:       Builds all of the modules in the current directory, and their dependencies.
- mmma:      Builds all of the modules in the supplied directories, and their dependencies.
- provision: Flash device with all required partitions. Options will be passed on to fastboot.
- cgrep:     Greps on all local C/C++ files.
- ggrep:     Greps on all local Gradle files.
- jgrep:     Greps on all local Java files.
- resgrep:   Greps on all local res/*.xml files.
- mangrep:   Greps on all local AndroidManifest.xml files.
- mgrep:     Greps on all local Makefiles files.
- sepgrep:   Greps on all local sepolicy files.
- sgrep:     Greps on all local source files.
- godir:     Go to the directory containing a file.

Environment options:
- SANITIZE_HOST: Set to 'true' to use ASAN for all host modules. Note that
                 ASAN_OPTIONS=detect_leaks=0 will be set by default until the
                 build is leak-check clean.
