请给我建议如何在springboot中选择兼容的依赖项,也许这就是我面临的问题所在。

Failed to execute goal on project demo: Could not resolve dependencies for project com.test.demo:demo:war:0.0.1-SNAPSHOT: 
    Failed to collect dependencies at org.apache.hadoop:hadoop-client:jar:3.3.0:

错误并不在于您有依赖性问题,而是maven无法导入依赖性(由于没有internet、代理设置等)。 Could not transfer artifact org.apache.hadoop:hadoop-client:pom:3.3.0 from/to central (https://repo.maven.apache.org/maven2): repo.maven.apache.org: Unknown host repo.maven.apache.org 看到了吗https://stackoverflow.com/a/20611947/13211030 同样的问题( Unknown host repo.maven.apache.org )以及一个可能的解决方案。
