Error with gradlew: /usr/bin/env: bash: No such file or directory

The problem's cause was that Git on Windows converted the line endings of gradlew from Unix style (LF) to Windows style (CRLF).

You can turn off that automatic conversion using git config core.autocrlf false.

Setting the line endings of gradlew back to Unix style fixed the problem. In Vim this is done using :set fileformat=unix.

This is because the gradlew file has Windows file-endings.

You can install dos2unix with apt-get or yum by running:

sudo apt-get install dos2unix

sudo yum install -y dos2unix

and then use dos2unix to convert the line-endings

from CRLF Windows CarriageReturn + LineFeed

to LF Linux LineFeed only:

dos2unix ./gradlew

Then run your gradlew for a test:

./gradlew clean -d
