目前多个组件依赖了不同的版本的guava库，升级时爆出xx类不存在，之前的库无法更新升级，如zk的curator,这个和zk版本强绑定，dubbo又依赖zk,系统中很多dubbo服务，根本不可能升级

can you just update guava library version to latest?

[cjdxhjj]

can't startup due to the no class def found error

[hezhangjian]

@cjdxhjj could please share the detail error msg or your depnendecy tree? :)

因为此类问题，spring 早就淘汰使用guava,但是其它库还在大量使用，目前我这个项目里就有16，20， 29
apollo 2.0.0依赖 31.0.1这么大的版本跨度下，每次更新依赖都是如履薄冰，一不小心就启动不了

Sorry for my late reply, I don't think spring remove guava for this reason, could you prove that? Spring update many dependencies frequently. Like bytebuddy/netty/prometheus-client.
Since you can't update guava dependency now. I suggest you shade apollo-client for now[1]. See https://www.jianshu.com/p/8171607ce03f

我觉得如果你们必需要用，应该使用你提供的方式将它嵌入在apollo的包中，并改包名，这样不会对其它包造成影响

[cjdxhjj]

那个包的api不兼容变更很常见，发布的也比较频繁

[cjdxhjj]

我觉得客户端根本不需要guice,一共没几个类，基本也就一个实现

[hezhangjian]

community has been discussed it before. you can share your feature request on #4369
If you are in a hurry, you can manually shade apollo package yourself.

目前我是使用方（有冲突），如果要从我这个地方解决的话，我需要重新打包apollo-client以应用shade插件

[cjdxhjj]

感觉还是解决掉这个麻烦（依赖）才是好的解决方案，目前jdk升级后，好多guava里的东西其实没啥价值了，远不如cats, zio, vavr,arrow-core等库方便好用

[nobodyiam]

This is an interesting topic to discuss. Apollo now requires guava 20.0+, can you upgrade to this version?
#4369 discusses the pros and cons of shading guava into apollo-client, and I think this may be the ultimate solution.

[cjdxhjj]

实际上我没看到是什么配置让guava降到16

[nobodyiam]

You could declare the guava version in the dependencyManagement section of your project's pom.xml, e.g.

<dependencyManagement>
    <dependencies>
        <dependency>
            <groupId>com.google.guava</groupId>
            <artifactId>guava</artifactId>
            <version>31.0.1-jre</version>
        </dependency>
    </dependencies>
</dependencyManagement>

[cjdxhjj]

好的，我得测试一下，不过不一定能升，启动后也可能随时爆出找不到类找不到方法的问题

[cjdxhjj]

我有好几个应用，依赖复杂点的应用用不了2.0。用1.6没问题,不过不兼容jdk 17,没有add opens
