I want to pass a VM argument in eclipse which is dependent on an environment variable.Something like this -

In Environment variables: var1=1234

In VM arguments: -Dvar2=%var1V78

This works properly without any issue using terminal but doesn't work in Eclipse

Eclipse encodes this '%' sign to '25', hence compiler is not able to find the value of 'var1' variable in 'var2'. Can anyone suggest on how to escape this '%' symbol or any other workaround.

In the launch configuration, in the VM arguments field use the env_var variable for a value of an environment variable as follows:

-Dvar2=${env_var:var1}5678

Use the button Variables... at the bottom of the VM arguments field to get a dialog that assists you in entering variables.

Please note, the env_var variable can only be used for environment variables that are visible in the process in which Eclipse is running.

In the launch configuration,

1. select the button 'Variables' below the VM arguments field.
2. On the Select Variables dialog, select 'env_var' from the list of variables. Enter Argument as 'var1'. Click 'Ok'
3. Now the VM argument will have format as ${env_var:var1} and edit it to have the format '-Dvar2=${env_var:var1}5678'
