Spring Boot Gradle bootRun task default classpath and current working directory

Question

I am going to test external config for application. What is default classpath and default working directory for Spring Boot Gradle bootRun task?

I didn't get in from:

• http://docs.spring.io/spring-boot/docs/current/reference/html/using-boot-running-your-application.html
• https://docs.spring.io/spring-boot/docs/current/reference/html/build-tool-plugins-gradle-plugin.html

UPDATE test with System.getProperty("user.dir") show that current directory is where Gradle is started.

Answer 1

Working directory is actually the module with Spring Boot project, which does not necessarily have to be the rootProject.

Classpath for bootRun is:

• working directory (or Gradle project directory with Spring Boot)
• main classes
• runtime classpath

At least this is what seems to be the default when I debug the build (now easily possible with IntelliJ IDEA 2018.2).
