The dependent version number in the dependencymanagement in the POM project parent in the idea is red

IDEA Managed as a dependency in parent Project pom In file , stay dependencyManagement Medium dependency, If the specified version does not exist in the local warehouse , And it will be reported in red if it is not quoted in the sub project , Don't understand at first , I thought that the package could not be downloaded , But in fact, I just quoted the very common dependency , And the version can be found on the official website .

After verification , In fact, this is a presentation problem , It doesn't affect the operation . I don't know this is a bug still IDEA Intentionally , Maybe it is suggested that we should not introduce it if we do not use it , But personally, I think it's a little too much , Yellow or grey is enough .
In short, this situation can be directly ignored , No impact on operation . Or delete parent In the project dependencyManagement The corresponding in dependency, Or first introduce the corresponding in the sub project dependency,maven I will download this version of the package , After that, you can remove the corresponding dependencies in the subproject ,parent There will still be no red in .

There are two conditions for reporting red in this case ：
1.parent Project dependencyManagement Specified in the dependency Version in maven There is no corresponding... In the local warehouse jar package （ The essence ）
2. This dependency is not referenced in the subproject （ Indirectly 1）
