Can't package biz code by use 4.0.0.

[chenshun00]

due to other reason , i can't use jdk1.8 . so i have to choose 4.0.0.

     <dependency>
            <groupId>io.kubernetes</groupId>
            <artifactId>client-java</artifactId>
            <version>4.0.0</version>
        </dependency>

when i run mvn clean compile -Dmaven.test.skip=true , my source code is gone . :(

again, remove it from pom, my source code is back .

due to other reason , i can't use jdk1.8 . so i have to choose 4.0.0.

how so? even the latest release (6.0.1) should be working w/ jdk 1.8.

my source code is gone . :(

probably caused by conflict between maven plugins.. how can i re-produce the issue?

[chenshun00]

@yue9944882 just a simple spring web app. compile by jdk1.7 . spring : 4.3.20.RELEASE

i have upload file to https://gitlab.com/chenshun00/war . Maybe it can help you。

@chenshun00 thanks, i fetched the source but didnt re-produce the issue in my local environment, the compiled classes always present regardless of whether commenting out the kubernetes sdk dependency or not.. am i missing anything?

@yue9944882 Maybe the problem with the jdk minor version . what your jdk minor version?

  <properties>
