@wu-sheng Here are the differences of dependencies between the dist package of my PR and the official dist 6.1.0 package (downloaded from the official website)

all the newly added dependencies are Apache 2.0 licenses, attachments are the dependencies names:

• aopalliance-1.0.jar
  

• apollo-client-1.4.0.jar

• apollo-core-1.4.0.jar
  
  

• guice-4.1.0.jar
  

• javax.inject-1.jar

I will follow this next week. Many new libs.

[kezhenxu94]

I've updated the newly-added dependencies list in my original comment, there're fewer because last time I compared the master branch with the latest released version, and there're some dependencies that are introduced by other commits (e.g. dependency io.sundr:sundr-core:jar:0.9.2 is introduced by this PR as a transitive dependency of kubernetes):

[wu-sheng]

I am back online. For this pull request, please read this PR #2640 . Your #2817 is easy to merge because of that.

All dependency libs must be added to LICENSE file in dist folder. For Apache 2.0, NOTICE file content should be added to our NOTICE. Other licenses should be copied. These include the io.sundr:sundr-core:jar:0.9.2, if we missed that when we updated the k8s client version.

[kezhenxu94]

These include the io.sundr:sundr-core:jar:0.9.2, if we missed that when we updated the k8s client version.

here is the differences between this PR (based on latest master branch) and the official release 6.1.0, and I'll base on the diff to add missing license or notice:

You need to cross check the difference between libs and existing license file.

@JaredTan95 Please review.
