Hi, I am getting this error now when running mvn spring-boot:run -Dspring-boot.run.arguments="--db_hostname=localhost:5432":

Is there a configuration I need to add?

Hi @Sigurdur42 what environment are you running this command, Windows Powershell? or CMD or another environment?

when running in Powershell the - needs to be escaped with a backtick. So in Powershell the command to run the application is: mvn spring-boot:run `-Dspring-boot.run.arguments="--db_hostname=localhost:5432"

Sigurdur42 commented 2 years ago

Hi @pimg, I am using the command line now. Maybe I do use the wrong java version?

set JAVA_HOME
JAVA_HOME=C:\Program Files\Java\jdk-17.0.3.1
pimg commented 2 years ago

Hi, you are using the correct JDK version.

Just for clarity this command works in Windows CMD: mvn spring-boot:run -Dspring-boot.run.arguments="--db_hostname=localhost:5432"

This command works in Windows PowerShell: mvn spring-boot:run `-Dspring-boot.run.arguments="--db_hostname=localhost:5432"

Hi, I just tried this again in windows cmd line: Just for clarity this command works in Windows CMD: mvn spring-boot:run -Dspring-boot.run.arguments="--db_hostname=localhost:5432"

Same error as before :(

Hi, in your original message (top of this thread) it mentioned:

Building DCSA-Core 0.8.33-SNAPSHOT

However this command: mvn spring-boot:run -Dspring-boot.run.arguments="--db_hostname=localhost:5432" needs to be issued in the BKG repository, so the output looks roughly like this:

C:\Users\User\workspace\dcsa\DCSA-BKG>mvn spring-boot:run -Dspring-boot.run.arguments="--db_hostname=localhost:5432"
