creating-your-first-micronaut-app-groovy's Issues

Tutorial fails on Micronaut 2.1.0 with Java 8

Environment:
Windows 10
Micronaut Version: 2.1.0
java version "1.8.0_261"
Java(TM) SE Runtime Environment (build 1.8.0_261-b12)
Java HotSpot(TM) 64-Bit Server VM (build 25.261-b12, mixed mode)

Followed the instructions, step 2, 3, 4. (did not download or clone from github).

Step 5: > Task :test FAILED. test results age shows:

org.gradle.api.internal.tasks.testing.TestSuiteExecutionException: Could not execute test class 'example.micronaut.CompleteSpec'.
Caused by: java.lang.UnsupportedClassVersionError: example/micronaut/CompleteSpec has been compiled by a more recent version of the Java Runtime (class file version 55.0), this version of the Java Runtime only recognizes class file versions up to 52.0
	at java.lang.ClassLoader.defineClass1(Native Method)

Step 6:

> Task :run FAILED
Error: A JNI error has occurred, please check your installation and try again
Exception in thread "main" java.lang.UnsupportedClassVersionError: example/micronaut/Application has been compiled by a more recent version of the Java Runtime (class file version 55.0), this version of the Java Runtime only recognizes class file versions up to 52.0
        at java.lang.ClassLoader.defineClass1(Native Method)

Interestingly: If I download the zip, cd into folder complete and then run "gradlew test" this does not produce the error above. The test completes without errors.

gradlew run lists errors (see below) but does start up. The browser however displays a json message "Page not found"

./gradlew test does not execute groovy tests

I am following the tutorial at https://guides.micronaut.io/creating-your-first-micronaut-app-groovy/guide/index.html and running the gradle command ./gradlew test does not run the spock specifications. Weirdly, it does it when I run it from IntelliJ.

The blaming part is

// use JUnit 5 platform
test {
    useJUnitPlatform()
}

in build.gradle file. Commenting out this part makes the trick.

Content type:json

By default this example returns a content-type: application/json, but it is returning a String. Some browsers will complain and not show the "Hello world"

package declaration incorrect

After cloning the repository the file complete/src/main/groovy/example/micronaut/Application.groovy uses:

package example

but should use

package example.micronaut

I had the problem that "example.micronaut.Application" could not be found when running gradle run

Update to Micronaut 2.0
