Spring Boot java.lang.IllegalArgumentException: URL must start with 'jdbc'

When trying to launch my project I get the error:

java.lang.IllegalArgumentException: URL must start with 'jdbc'

I configure my database connection in an application.properties file that looks like this:

spring.datasource.url=${JDBC_DATABASE_URL}
spring.datasource.username=${JDBC_DATABASE_USERNAME}
spring.datasource.password=${JDBC_DATABASE_PASSWORD}

And have an maven/spring-boot start script that gets the VM options:

-DJDBC_DATABASE_URL="jdbc:postgresql://localhost:5432/project"
-DJDBC_DATABASE_USERNAME="postgres"
-DJDBC_DATABASE_PASSWORD="postgres"

A few tests showed me, that the VM options are completely not resolved but I have no idea on how to fix this.

My IDE is IntelliJ Community Edition.

It worked fine. Today I upgraded the project to Java 15 but in my opinion this should not result in such a problem.

Do you have any idea where the config gets overwritten or something?

When you quote just the value, the quote characters become part of the value, which means that the URL now starts with a "jdbc, so you get error saying "must start with jdbc".

You have two options:

  1. Don't quote:

    -DJDBC_DATABASE_URL=jdbc:postgresql://localhost:5432/project
-DJDBC_DATABASE_USERNAME=postgres
-DJDBC_DATABASE_PASSWORD=postgres

  2. Quote the whole argument:

    "-DJDBC_DATABASE_URL=jdbc:postgresql://localhost:5432/project"
"-DJDBC_DATABASE_USERNAME=postgres"
"-DJDBC_DATABASE_PASSWORD=postgres"
