Minecraft Forums

I have been running through several problems lately since I bought a new computer. I was working on a mod for a game called Grand Chase on my old computer. Everything was working perfectly until I bought this computer. At first, the error I had was "Open Project has encountered a problem" every time I tried to open the Minecraft folder inside the eclipse. (https://www.minecraftforum.net/forums/mapping-and-modding-java-edition/minecraft-mods/modification-development/2982622-open-project-has-encountered-a-problem-minecraft). Now as I was trying again to work on my mod, I ran through another error which I have no clue on how to fix it. After I downloaded eclipse, added the environment variables and downloaded the forge for 1.7.10, I tried to run the gradlew commands on the command prompt but it says the following:

FAILURE: Build failed with an exception.

* What went wrong:
A problem occurred configuring root project 'GrandChaseMod'.

Can someone help me please?!!!!!

I got the exact same thing. 1.7.10 no longer works I believe. I have come to the conclusion one of the downloads no longer works. Time to upgrade ;(

That is really sad because I wanted to play my mod with the Dragon Block C

;(

thanks for the reply!!

If you click on one of the URLs given you get this error:

501 HTTPS Required.
Use https://repo1.maven.org/maven2/
More information at https://links.sonatype.com/central/501-https-required

I'm not sure exactly where it is but you have to change "http" to "https" in a configuration file (I've seen this said to be the solution in similar reports, the files would be in MCP or whatever Forge uses for its development environment and you can do a file search for "http://repo1.maven.org" to find it). The downloads do appear to work once this is done so the files still exist online; for example:

http://repo1.maven.org/maven2/org/eclipse/equinox/app/maven-metadata.xml (broken)
https://repo1.maven.org/maven2/org/eclipse/equinox/app/maven-metadata.xml (working)

Also, I'd suggest making a backup of the development environment once you get it working, as I've done for my MCP 1.6.4 environment (after fully decompiling it and everything so all the game libraries and assets are included, including making a backup of the unmodified source files so I can simply copy them over when I want to start modding from scratch; of course, Forge wouldn't have such files as you don't modify the game directly); when I last got a new computer I simply copied the entire folder over with no issues (I just had to re-do the JDK environment variables).

You all should search the threads for issues before re-posting this same issue. There is a fix.

ok

thank you, ill try that!!

Sorry for the necropost, but I have the exact same problem, and I've been trying to fix it for the past few hours. http://repo1.maven.org doesn't exist anywhere on my computer, and I can't find anything to do with Maven and http, even in the build.gradle file.

I've been on every post that I can find about this issue on the internet, and nothing helps. Usually everything is so cryptic I have no idea what to do with the information given, so I end up trying everything I can think of and still nothing works. Do I have to do something in Eclipse? And where?

I've changed every http I can find to https, but it still throws that exact same https required crud.

Can anyone explain what to do in a clear and concise manner?

Don’t necro old threads create your own btw,

I fixed this by updating the gradle version that Forge uses.

Go to \gradle\wrapper in your project root directory and modify gradle-wrapper.properties file:

change

distributionUrl=https\://services.gradle.org/distributions/gradle-2.0-bin.zip

to

distributionUrl=https\://services.gradle.org/distributions/gradle-2.6-all.zip
