not required, remove the directory instead (using @code{prebuild} for
example).
-@item maven=yes
-Build with maven instead of ant
-
@item gradle=<flavour>[@@<dir>]
Build with gradle instead of ant, specifying what flavour to assemble.
If <flavour> is 'yes', 'main' or empty, no flavour will be used. Note
directory. This might be necessary if gradle needs to be run in the parent
directory, in which case one would use 'gradle=<flavour>@..'.
+@item maven=yes[@@<dir>]
+Build with maven instead of ant. Like gradle, an extra @@<dir> tells f-droid
+to run maven inside that relative subdirectory.
+
@item preassemble=<task1> <task2>
Space-separated list of gradle tasks to be run before the assemble task
in a gradle project build.
