I'm trying to download SevTech Ages and am getting the same type of errors. It looks like the files that are unable to be downloaded have special characters in them like brackets, spaces, "+" sign, etc. It results in a broken download link I believe. Just my 2 cents. Hope that helps.

[frenchiveruti]

Use multiMC.

[abortu]

@frenchiveruti, this program is how you download the modpack from curse to import into MultiMC. That's what I was trying to do. The correct workaround is use ATLauncher at least for SevTech, it's in there. It's not in MultiMC as it's not an FTB pack or one that's in their list.

Update Importing the zip from curse into MultiMC did download the mods and import correctly. I was under the impression from their github issues that it didn't work currently. Thanks for the tip! However, the bug is still a bug here. I suspect its from encoding/decoding the mod URL's incorrectly in CMPDL. URL's have to be converted properly or the special characters are incorrect. It looks like the special characters are being escaped twice incorrectly.

This line is the important one: "Downloading Pam%27s HarvestCraft 1.10.2j.jar"
It gets escaped into

https://media.forgecdn.net/files/2428/363/Pam%2527s+HarvestCraft+1.10.2j.jar

%25 is the HTML equivalent of "%"
It's double escaping. %25%27 decodes to %' when it should only be %27.

Hope that helps.

I know, but I haven't seen Vazkii reply anything in this github for the last 4 months.

For anyone still looking for a solution, you can download the problematic .jar files yourself from the curse page, and the program will detect the file as already existing. Make sure you download the .jar file corresponding to the Minecraft version. This fixed the solution for me and still saved me the hassle of installing everything manually. Just find the directory where it's installing everything to and drag the .jar in there.

This is @Vazkii For you. Sadly comes with great ideas but never really finishes them. I'm also looking for a solution command line based.

You might try one of the various forks that folks are maintaining.

[draeath]

The fork by MrLavender appears to have a commit addressing this issue, in fact.

It seems to be working, for me. Note that the resulting files on-disk will have some of the offending characters stripped. Be aware of this, I would clean out the C:\Users\draeath\.cmpdl_temp directory (fix your username of course, non-windows it's probably ~/.cmpdl_temp but I'm unsure) to ensure you don't end up with redundant-but-differently-named files in the final instance.
