A shell script is a very versatile way to extend your build to basically anything you can think of.
As an exmaple, here is a simple script to compile protobuf files and add the result java files to the source directory for further compilation:
def compilePb() {
exec {
// NOTICE: gradle will fail if there's an error in the protoc file...
executable "../pbScript.sh"
}
}
project.afterEvaluate {
compilePb()
}The ‘pbScript.sh’ shell script for this example, located in the project’s root folder:
#!/usr/bin/env bash
pp=/home/myself/my/proto
/usr/local/bin/protoc -I=$pp \
--java_out=./src/main/java \
--proto_path=$pp \
$pp/my.proto \
--proto_path=$pp \
$pp/my_other.proto
