Create Java Function
Creates a Java function within the repository system.
create function <func_name> as <path.to.package.Func> using '<package.jar>'; create function <func_name> as <path.to.package.Func> using '<package.jar>'; #!/bin/bash
# Create Java Function
create function {{func_name}} as {{path.to.package.Func}} using '{{package.jar}}'; import subprocess
# Create Java Function
# Make sure to replace <placeholders> with actual values
def run_command():
cmd = [
"create",
"function",
"<func_name>",
"as",
"<path.to.package.Func>",
"using",
"'<package.jar>'",
";"
]
try:
print(f"Executing: {' '.join(cmd)}")
subprocess.run(cmd, check=True)
except subprocess.CalledProcessError as e:

run_command() When To Use
When integrating Java-based functionality into the project.
Pro Tip
Ensure the JAR file is correctly built and accessible to avoid runtime errors.
Command Builder
Tune the command before you copy it
create function <func_name> as <path.to.package.Func> using '<package.jar>'; Anatomy of Output
Understanding the result
Creating function '{{func_name}}' from '{{path.to.package.Func}}'. Function Creation Status Indicates progress in creating the function.
Using JAR file located at '{{package.jar}}'. Archives Location Specifies where the binary is sourced.
Function '{{func_name}}' created successfully! Completion Message Final confirmation of successful creation.
Troubleshooting
Common pitfalls
ERROR: JAR file '{{package.jar}}' not found.
Solution: Double-check the JAR path and ensure file availability.
ERROR: Class '{{path.to.package.Func}}' does not exist.
Solution: Validate that the class is compiled and accessible.
ERROR: Invalid function name '{{func_name}}'.
Solution: Ensure function name adheres to naming conventions.
