consume Bamboo variables directly into java

[SidduAngadi]

Hi,

Currently I am passing bamboo variable into custom java progam as below:

-Drlm.PlanName=${bamboo.planName} -jar  get.jar

I would like not to pass ${bamboo.planName} through property.  is there anyway to consume this variable directly into external java program. say example:

-jar get.jar

should print ${bamboo.planName} variable value.

Thanks

Siddu

Hello Siddu,

The "${bamboo.planName}" is a variable that is created during execution time and it is for Bamboo's internal use. However, you are able to get the environment variable version ("bamboo_planName").

You are able to run the following Java code and compile it just to make sure the variable can be printed, however, replying to your inquire the same should be called as System.getenv("bamboo_planName") in your Java code.

import java.util.Map;
public class EnvMap {
	
    public static void main (String[] args) {
        Map<String, String> env = System.getenv();
        for (String envName : env.keySet()) {
            System.out.format("%s=%s%n",
                              envName,
                              env.get(envName));
        }
		
		System.out.println(":: PlanName :: " + System.getenv("bamboo_planName"));
    }
}

Go to Bamboo and add a Script task to your plan as per following:

echo "# =========================== #"
echo "# Compile the Program"
echo "# =========================== #"
javac EnvMap.java

echo "# =========================== #"
echo "# Create manifest"
echo "# =========================== #"
echo "Main-Class: EnvMap" > manifest.txt


echo "# =========================== #"
echo "# Create jar"
echo "# =========================== #"
jar cvfm EnvMap.jar manifest.txt *.class


echo "# =========================== #"
echo "# Execute JAR"
echo "# =========================== #"
java -jar EnvMap.jar

In the build result you will find all the environment variables available to the build you are running along with the following entry:

...
build	15-Oct-2015 12:11:15	:: PlanName :: Project - Plan
...

If you find this answer useful, I would kindly ask you to accept it so the same will be visible to others who might be facing the same issue you have inquired.

Thank you for your understanding.
