'Getting a date in properties file in string format

I want to get a date from a key dynamically which will be used by java program to perform some tasks.

I have to get values from property file to java. cannot do vice versa

So basically the value for this key, job.date=2022-03-23 i can get through date -d tomorrow "+%Y-%m-%d". But this works fine when job.date is accessed from shell script and gives a parsing error when accessed from java class.

so looking for java understandable snippet, or a way to override it while executing the java class with jar

Solution 1:[1]

You should use (if this is the property and value you want)

java -Djob.date=$(date -d tomorrow +"%Y-%m-%d") ...

Solution 2:[2]

java -Djob.date=$(date -d tomorrow +"%Y-%m-%d") ...

The above gave me exception, error loading main class.

It worked with following snippet:

sed -i "s/\(testauto\.as\.of\.date=\).*\$/\1${tomorrow}/" abc.properties

Added this line in shell script that was calling the java class.
