Classloader problems with spaces on project path

[janchristian-haddorp]

With the Spring Boot 3.0.3 there is a classloader issue if the project path contains spaces. Same setup works with Spring Boot 3.0.2.

The behaviour could be reproduced on Windows 10 and on macOS.

In our case the Liquibase config XML could not be loaded. However, this is not a pure Liquibase issue. Other configurations, e.g. security config, cause similar effect.

Application is built and started with Gradle...

./gradlew bootRun

Removing spaces from project path and everything works fine.

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'liquibase' defined in class path resource [org/springframework/boot/autoconfigure/liquibase/LiquibaseAutoConfiguration$LiquibaseConfiguration.class]: The file classpath:db/changelog/changelog.xml was not found in the configured search path:
    - Spring classpath
More locations can be added with the 'searchPath' parameter.
