Composite Builds Hierarchical Multirepo Sample - fails when following the instructions

[maol74]

Expected Behavior

When download groovy sample zip for example https://docs.gradle.org/current/samples/sample_composite_builds_hierarchical_multirepo.html, unpack it and following the instruction the build fails

• when running .\gradlew publishDeps it fails, example uses maven repo during publish not Ivy as configured
• after cloning commons-lang, when running gradle --project-dir modules/commons-lang build the build fails during javadoc
• after cloning commons-lang, when running gradle build the build fails with following error

* What went wrong:
Circular dependency between the following tasks:
:commons-lang:classes
\--- :commons-lang:compileJava
     \--- :commons-lang:jar
          \--- :commons-lang:classes (*)

Looks like that sample expects too much to happen with defaults only. It most likely need a number of changes so that what it documents work ... and keeps working.

I was most concerned about the Circular dependency error, can´t understand why that happens, could that be a bug?

There were definitely a lot of things wrong with this sample. Personally, I was not able to reproduce the circular dependency error you were seeing, but I was able to reproduce the rest. Following the directions line-by-line did not produce the circular dependency problem. Did you make any manual modifications to the sample files which may have caused that error?

Hi!
You should be able to reproduce the "Circular dependency" error by doing this when clone the commons-lang project

1. git clone http://gitbox.apache.org/repos/asf/commons-lang.git modules/commons-lang --branch master --depth 1
2. ./gradlew --project-dir modules/commons-lang init
   I choose yes, 1, yes in the init questions
3. ./gradlew run

Note that I´m using gradlew from root project, standing in root dir. I also cloned out master instead. Could also be the init choices perhaps, I choose yes, 1, yes?

FAILURE: Build failed with an exception.
