Cole Faust 1269a74fad Make pom2bp output preprocessed: true on app imports
The only difference between preprocessed + presigned vs just presigned
is that just presigned will zip align the apk, and preprocessed +
presigned will instead check that the apk is already aligned and has
uncompressed jni and dex libs. This should be the default to ensure
we're getting valid apk imports from external sources.

Presigned alone also won't work for apps with target sdk >= 30, because
on those target sdks you have to use apk signature v2, and having the
build system align the zip file will break that signature.

Bug: 185811447
Test: Presubmits

fmt.Fprintf(os.Stderr, `pom2bp, a tool to create Android.bp files from maven repos
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).
