Failed to install MStest plugin : Jenkins - jenkins

Question

I try to install the MSTest for showing the results from .trx file.
As I install through Download Now and Install after Restart, My Jenkins is taking so long time to restart so I tried with Install without restart.
It shows the following error

Answer 1

It is because MSTest plugin depends on emma and maven-plugin. I suspect you have bad network condition while download these 2 dependencies.
First, try Download Now and Install after Restart but wait for a longer time until it get successfully installed. Jenkins will take care of the dependencies.
Or,
as an alternative, you can first install emma and maven-plugin, then install MSTest then.
