Compile classpath in case of dependency conflict

[Rimvydas Vaidelis]

Hello,

I have 2 dependencies org.reflections:reflections:jar:0.9.8:test and
com.google.inject:guice:jar:5.1.0:compile.
org.reflections:reflections:jar:0.9.8 uses
com.google.guava:guava:jar:11.0.2:compile
com.google.inject:guice:jar:5.1.0 uses
com.google.guava:guava:30.1-jre:compile

During compiling of the module (mvn compile) the compile classpath contains
guava-11.0.2.jar. Why? It seems
that occurrence of version conflict changes the scope of the transitive
dependency com.google.guava:guava:jar:11.0.2 to compile.
Is this an expected behavior?

Dependency tree:

org.example:dependency-conflict-example:jar:1.0-SNAPSHOT
+- org.reflections:reflections:jar:0.9.8:test
|  +- com.google.guava:guava:jar:11.0.2:compile
|  |  \- com.google.code.findbugs:jsr305:jar:1.3.9:compile
|  +- javassist:javassist:jar:3.12.1.GA:test
|  \- dom4j:dom4j:jar:1.6.1:test
\- com.google.inject:guice:jar:5.1.0:compile
   +- javax.inject:javax.inject:jar:1:compile
   \- aopalliance:aopalliance:jar:1.0:compile
