Spring Rest Doc (Gradle) Snippets disappear upon build - spring-restdocs

Question

Recently switch to Gradle from Maven.
Following this tutorial for continuous REST Doc build with Gradle. https://www.youtube.com/watch?v=k5ncCJBarRI&t=1490s
Snippets are generating just fine when running test. Its when I am trying to generate asciidoc where it seems like the /build directory gets recreated without the snippets. So my generated html always shows
Unresolved directive in index.adoc - include::{snippets}/home-json/curl-request.adoc[]
I am generating the asciidoc by the following command in the terminal
gradle asciidoctor -t
// Continuous build command
// Mentioned around #1:07:40 mark

developmentOnly 'org.springframework.boot:spring-boot-devtools'
}
test {
outputs.dir snippetsDir
useJUnitPlatform()
}
asciidoctor {
inputs.dir snippetsDir
dependsOn test

}
}
MyTest
#RunWith(SpringRunner.class)
#SpringBootTest
#AutoConfigureMockMvc
public class HelloControllerTest {
#Autowired
private MockMvc mockMvc;
#Rule
public final JUnitRestDocumentation restDocumentation = new JUnitRestDocumentation();
#InjectMocks
private HelloController helloController;
#Mock
private HelloService helloService;
#Before
public void setUp() throws Exception {
// create a mock environment of helloController
mockMvc = MockMvcBuilders.standaloneSetup(helloController)
.apply(documentationConfiguration(this.restDocumentation))
.build();
}
#Test
public void shouldReturnDefaultMessage() throws Exception {
this.mockMvc.perform(get("/hello/string"))
.andDo(print())
.andExpect(status().isOk())
.andExpect(content().string(containsString("hello there"))
)
.andDo(document("home-string"));
}
I also checked my build.gradle against https://spring.io/guides/gs/testing-restdocs/ and https://docs.spring.io/spring-restdocs/docs/2.0.5.RELEASE/reference/html5/#configuration-uris. I don't know what I am missing...
Thanks in advance.
Edited
Ran command gradle asciidoctor --console=plain
If it makes it easier I greated a Git repo

Answer 1

When run from the command line, you build isn't running any tests. The tests aren't being run as your tests are using JUnit 4 while the test task has been configured to use the JUnit Platform (JUnit 5):
test {
outputs.dir snippetsDir
useJUnitPlatform()
}
You can fix the problem either by updating your tests to use JUnit 5 or by removing useJUnitPlatform() from the test task's configuration so that it uses JUnit 4. The latter is the smaller change and leaves the test task looking like this:
test {
outputs.dir snippetsDir
}
