Utility script to find and run the nearest gradle wrapper.

README.md

Installation

1. Download the raw script: curl -o ~/.local/bin/gradlew https://gist.githubusercontent.com/mpetuska/86c05e02b2199e5a2f186da0c2c3f2fd/raw/gradlew.sh
2. Adjust permissions: chmod +x ~/.local/bin/gradlew
3. (Optional) Make a shortcut: ln -s ~/.local/bin/gradlew ~/.local/bin/gw

There's also an installation script available:

curl https://gist.githubusercontent.com/mpetuska/86c05e02b2199e5a2f186da0c2c3f2fd/raw/installGW.sh | bash

Usage

With this script setup, you can invoke gradle commands from any directory in multi-module project via nearest wrapper. The script supports both, nested and flat module structure.

Here's an example nested project structure

/parent
  /moduleA
  /moduleB
    /moduleC

With the structure above, you can invoke gradlew or gw command from any child subdirectory and automatically target that module's tasks. For instance the following will invoke :moduleA:test task only from parent's gradlew.

# pwd - /parent/moduleA
gw test

This also works with flat gradfle project structure

/parent
/moduleA
/moduleB
  /moduleC

gradlew.sh

#!/usr/bin/env bash

currentDir=`pwd`
targetDir=$currentDir

gradlewFile=`pwd`/gradlew
function find-gradlew() {
    gradlewFile=`find $1 -name gradlew | head -n 1`
}

while [[ -d ${targetDir} ]]; do
    if [[ -f ${gradlewFile} ]]; then
        targetDir=`echo ${gradlewFile} | sed -e "s/\/gradlew$//"`
        targetDir=`cd ${targetDir}; pwd`
        gradlewFile=${targetDir}/gradlew
        root=`(cd ${targetDir}/..; pwd)`
        if [[ ${currentDir} =~ ^${targetDir} ]]; then
        	root=${targetDir}
        fi
        
        gradlePath=`echo ${currentDir} | sed -e "s:^${root}::" | sed -e "s:/:\::g"`
        args=""
        if [[ ${targetDir} != ${currentDir} ]]; then
            for arg in "$@" ; do
                if [[ ${arg::1} =~ [-\'\":] ]]; then
                    args="${args} ${arg}"
                else
                    args="${args} ${gradlePath}:${arg}"
                fi
            done
        else 
            args="$@"
        fi
        
        commandLine="${gradlewFile} -p ${targetDir} ${args}"
        echo Working Directory: ${currentDir}
        echo Executing: ${commandLine}
        bash ${commandLine}
        exit 0
    else
        targetDir=${targetDir}/..
        find-gradlew ${targetDir}
    fi
done
exit 1
