Hi! I found the pom file of project de.ruedigermoeller:kontraktor-web:4.30 introduced 54 dependencies. However, among them, 11 libraries (20%) are not used by your project. I list the redundant dependencies below (labelled as red ones in the figure):
Redundant dependencies
org.codehaus.mojo:animal-sniffer-annotations:jar:1.14:compile
com.google.jsinterop:jsinterop-annotations:jar:1.0.0:compile
com.google.code.findbugs:jsr305:jar:3.0.1:compile

Removing the redundant dependencies can reduce the size of project and prevent potential dependency conflict issues (i.e., multiple versions of the same library). More importantly, one of the redundant dependencies org.jboss.spec.javax.servlet:jboss-servlet-api_3.1_spec:jar:1.0.0.Final:compile incorporates an incompatible license COMMON DEVELOPMENT AND DISTRIBUTION LICENSE (COMMON DEVELOPMENT AND DISTRIBUTION LICENSE cannot be used by the project with license LGPL 3), one of the redundant dependencies org.jboss.spec.javax.websocket:jboss-websocket-api_1.1_spec:jar:1.1.0.Final:compile incorporates an incompatible license COMMON DEVELOPMENT AND DISTRIBUTION LICENSE (COMMON DEVELOPMENT AND DISTRIBUTION LICENSE cannot be used by the project with license LGPL 3). As such, I suggest a refactoring operation for de.ruedigermoeller:kontraktor-web:4.30’s pom file.
The attached PR helps resolve the reported problem. It is safe to remove the unused libraries (we considered Java reflection relations when analyzing the dependencies). These changes have passed de.ruedigermoeller:kontraktor-web:4.30’s maven tests.
