Build failed due to a user error: build script returned non-zero exit code: 2

Explanation:

When you encounter a build failure with the error message “build failed due to a user error: build script returned non-zero exit code: 2,” it means that the build process was unsuccessful due to an error in the user’s script, and the script returned a non-zero exit code (in this case, 2) indicating the failure.

It’s important to carefully review your build script, as user errors can occur due to various reasons such as syntax errors, invalid file paths, missing dependencies, or incorrect command usage.

To resolve this issue:

1. Check your build script for any syntax errors. Ensure that all commands are properly formatted and any variables or functions are correctly defined.
2. Verify that file paths used in the script are correct. Make sure the files exist and are accessible.
3. Check for any missing dependencies or libraries required by your build script. Install any missing dependencies or update existing ones to the required versions.
4. Review the commands used in the script. Ensure that the commands are being used correctly, with the appropriate arguments and options.

Here’s an example to illustrate this situation:

build.sh:

#!/bin/bash
echo "Building project..."
./compile.sh  # This line is causing the error
if [ $? -eq 0 ]; then
  echo "Build successful!"
else
  echo "Build failed!"
  exit 2  # Non-zero exit code indicating the failure
fi

compile.sh:

#!/bin/bash
echo "Compiling source code..."
gcc -o myapp main.c  # Assuming main.c is missing, this line will fail

In this example, the build.sh script attempts to build a project by calling the compile.sh script. However, the compile.sh script tries to compile a main.c file that doesn’t exist, resulting in a failed build with a non-zero exit code of 2.

By carefully reviewing and debugging your build script, you can identify the user error causing the build failure and make the necessary corrections to ensure a successful build.
