Diamant is leaking JUnit 4.10 as a transitive dependency

[errantlinguist]

As of 2018-06-1 with commit 700921a5af of DialogOS (which uses Diamant commit 700921a5af), JUnit 4.10 is leaked to the compile configuration (note: not testCompile) for software which depends on DialogOS. This breaks compilation for tests that use 4.12 due to e.g. additional methods in the latter:

./gradlew dependencyInsight --configuration compile --dependency junit
Parallel execution is an incubating feature.

junit:junit:4.10

          +--- com.github.coli-saar:dialogos:master-SNAPSHOT:700921a5af-1

When built using the Gradle wrapper ./gradlew build, there is no issue. However, when building through Eclipse using Eclipse's Gradle plugin, the version from compile takes precedence over testCompile.

Build environment:

• Gradle wrapper 4.7
• openjdk build 1.8.0_171-8u171-b11-0ubuntu0.16.04.1-b11
• Linux kernel 4.13.0-43-generic (Linux Mint 18.3 Sylvia)
• Eclipse IDE for Java Developers
  • Version: Oxygen.3a Release (4.7.3a)
  • Build id: 20180405-1200
  • OS: Linux, v.4.13.0-43-generic, x86_64 / gtk 3.18.9, WebKit 2.4.11
• Eclipse Gradle plugin ("buildship") 2.2.1.v20180125-1441

hm. so it's actually json-simple that is leaking the dependency. I think this bug is somewhere between json-simple (unmaintained) and eclipse (hard to negotiate with). Thus I'm marking this as wontfix. However, I opened #76 because we really should not be using two JSON libraries and json-simple is probably the right one to go.

fixed by #76.
