junit5-spring-boot

- Demo-Project to reproduce junit-team/junit5#1724

How to build and run:

cd junit5-spring-boot

mvn clean package
java -jar junit5-spring-boot-application/target/junit5-spring-boot-application-1.0.0-SNAPSHOT.jar

Observed Behaviour:

• When executed within an IDE which uses a regular classpath, the tests are executed
• When executed as Spring Boot JAR, the tests are not executed
• When executed with a class selector, the tests are executed

Possible Cause

The junit5-spring-boot-tests JAR which contains the tests is located in BOOT-INF/lib within the junit5-spring-boot-application JAR. JUnit tries to load the class by executing Files.walkFileTree() which seems not to work with nested JAR files.
