To retrieve environmental variables using Java in Github Action, you can use the System.getenv()
method.
Example code:
String variableValue = System.getenv("VARIABLE_NAME");
System.out.println(variableValue);
Replace VARIABLE_NAME
with the name of the environmental variable you want to retrieve.
Make sure that the environmental variable is set in the Github Action workflow before you retrieve it using Java. You can set a new value for an environmental variable using the env
keyword in the workflow file.
Example workflow:
name: My Workflow
on: [push]
jobs:
build:
runs-on: ubuntu-latest
steps:
- name: Set Environmental Variable
run: echo "VARIABLE_NAME=value" >> $GITHUB_ENV
- name: Run Java Code
run: java MyJavaClass
In the above example, the Set Environmental Variable
step sets a new value for the VARIABLE_NAME
environmental variable using the echo
command. The value
can be replaced with any desired value.
The Run Java Code
step then runs the MyJavaClass
program, which can use the System.getenv()
method to retrieve the value of VARIABLE_NAME
.
