This demo shows that Spring Boot 2 custom actuator endpoints require the -parameters
compiler option to work when compiled with Gradle.
The Spring Boot Gradle Plugin configures the compiler option automatically, but when you are a framework developer and don't use the Spring Boot Gradle Plugin you have to add the option yourself.
The test fails, but when you uncomment options.compilerArgs += ["-parameters"]
in the build.gradle
file, the test is successful.
