| |
| The tool will extract the necessary information from *.pom files to create an Android.bp whose |
| aar libraries can be linked against when using AAPT2. |
| |
| Usage: %s [--rewrite <regex>=<replace>] [--exclude <module>] [--extra-static-libs <module>=<module>[,<module>]] [--extra-libs <module>=<module>[,<module>]] [--optional-uses-libs <module>=<module>[,<module>]] [<dir>] [-regen <file>] |
| |
| -rewrite <regex>=<replace> |
| rewrite can be used to specify mappings between Maven projects and Android.bp modules. The -rewrite |
| option can be specified multiple times. When determining the Android.bp module for a given Maven |
| project, mappings are searched in the order they were specified. The first <regex> matching |
| either the Maven project's <groupId>:<artifactId> or <artifactId> will be used to generate |
| the Android.bp module name using <replace>. If no matches are found, <artifactId> is used. |
| -exclude <module> |
| Don't put the specified module in the Android.bp file. |
| -extra-static-libs <module>=<module>[,<module>] |
| Some Android.bp modules have transitive static dependencies that must be specified when they |
| are depended upon (like android-support-v7-mediarouter requires android-support-v7-appcompat). |
| This may be specified multiple times to declare these dependencies. |
| -extra-libs <module>=<module>[,<module>] |
| Some Android.bp modules have transitive runtime dependencies that must be specified when they |
| are depended upon (like androidx.test.rules requires android.test.base). |
| This may be specified multiple times to declare these dependencies. |
| -optional-uses-libs <module>=<module>[,<module>] |
| Some Android.bp modules have optional dependencies (typically specified with <uses-library> in |
| the module's AndroidManifest.xml) that must be specified when they are depended upon (like |
| androidx.window:window optionally requires androidx.window:window-extensions). |
| This may be specified multiple times to declare these dependencies. |
| -sdk-version <version> |
| Sets sdk_version: "<version>" for all modules. |
| -default-min-sdk-version |
| The default min_sdk_version to use for a module if one cannot be mined from AndroidManifest.xml |
| -use-version <version> |
| If the maven directory contains multiple versions of artifacts and their pom files, |
| -use-version can be used to only write Android.bp files for a specific version of those artifacts. |
| -write-cmd |
| Whether to write the command line arguments used to generate the build file as a comment at |
| the top of the build file itself. |
| -jetifier |
| Sets jetifier: true for all modules. |
| <dir> |
| The directory to search for *.pom files under. |
| The contents are written to stdout, to be put in the current directory (often as Android.bp) |
| -regen <file> |
| Read arguments from <file> and overwrite it (if it ends with .bp) or move it to .bp (if it |
| ends with .mk). |
