Warning: Package xxxxx does not have POMDPSimulators in its dependencies in Julia if usual recommendations don't work.

I have seen this issue commonly since I started the transition to Julia v0.7 from v0.6. I am getting the following warning: 

 Warning: Package xxxxx does not have POMDPSimulators in its dependencies:
│ - If you have xxxxx checked out for development and have
│   added POMDPSimulators as a dependency but haven't updated your primary
│   environment's manifest file, try `Pkg.resolve()`.
│ - Otherwise you may need to report an issue with xxxxx
└ Loading POMDPSimulators into xxxxx from project dependency, future warnings for xxxxx are suppressed.

I do not understand why I get this warning. In one of my files, I do: using POMDPSimulators. Since I typed in that, I have done a resolve in the Pkg manager, and done a build POMDPSimulators in the package manager. This doesn't change the warning. How can I get rid of this warning?

Note: xxxxx is just the name of a file/project that is removed to make this post general.

Note: I asked a similar question here: [Julia ERROR: LoadError: ArgumentError: Package xxxx does not have ExcelReaders in its dependencies:

I already checked out the Julia documentation and did what it says. I added the package to the project by using the package manager and typing add POMDPSimulators.

Any suggestions to resolve this issue?

Note: If possible, I am looking for a general answer since I think I am going to have this issue with other packages as well. If there is any other documentation out there besides what was provided by JuliaLang I could appreciate that since I didn't find it helpful.

Link to the Julia Article about dependencies

I tried a pkg> update, build, and resolve. The issue isn't resolved. I see the file in my Manifest and Project file.

Possible duplicate of Julia ERROR: LoadError: ArgumentError: Package xxxx does not have ExcelReaders in its dependencies:. If the answer there was not satisfactory it is better you ask for clarification there. – fredrikekre
I don't think it was a duplicate. That issue was resolved by doing something else. I would delete that question, but I think there is tangible knowledge to be gained by someone looking at it. – logankilpatrick

Here is what got the Warning to no longer show for me.

Go to your require file and type "NameOfPackageGivingWarning" on a new line.

Click "]" in Julia to open the package manager in Julia command line version:

up NameOfPackageGivingWarning

build NameOfPackageGivingWarning

resolve

activate NameOfPackageGivingWarning

This should resolve the issue for you. I am honestly unsure why this works and I may be taking more steps than necessary, but it resolved the issue for all of my package dependency warnings!
