4. Synchronize the version Library
Using the repo sync command, we synchronize the entire android code tree to the local device. Similarly, we can use

. That is to say, after the variant is specified in the compilation command, during the execution, the script compares the value of variant with the tag value set in each sub-project. If the match is found, compile the sub-project and add it to the output path of the product, otherwise, no compilation is performed;Note: The tag and variant are not exactly one-to-one, for example:
Optional indicates that it is optional, that is, it is not required to run the
