While trying to publish an iOS app via Xcode, and after passing most of validations, I received the following error:
A downloaded software component is corrupted and will not be used. https://contentdelivery.itunes.apple.com/transporter/repositories/j2se8/1.12.0/bundles/com.apple.transporter.mediatoolkit-1.12.0.jar
Actually, I'm running MacOS High Sierra on VMware
Tried to re-upload the binary again and it worked without doing any changes to it :-) First time it did not, but the second time it was uploaded.
When uploaded, triggered this issue: ITMS-90381: Too many symbol files - These symbols have no corresponding slice in any binary [1563DEE7-9CA4-3E32-A685-59C6096A7559.symbols, 0C5A429A-9899-3DBC-B2BF-130063489259.symbols
Need to Google that to see it can be resolved! :-) but it's just a warning, the binary was accepted.
