failure to build

[wzydhek]

I am trying to build jd-gui on my window system. I followed the snippet on the readme "How to build JD-GUI ?"

git clone https://github.com/java-decompiler/jd-gui.git
cd jd-gui
./gradlew build

and it gives me an error:

FAILURE: Build failed with an exception.

• What went wrong:
  A problem occurred configuring root project 'jd-gui'.

Try the steps in this issue and see it helps

ok again, I am new to gradle, but managed to get it to pull the dependency for launch4j. Having problems getting it to pull the dependency jd-core-1.1.3. the link maven's repository has leads to file not found

List the steps it would help me know what you might have done wrong.

The issue I have referenced talks about the same thing you are facing at least to an extent, implement them and give the error here.

I did the steps mentioned iin the readme.

git clone https://github.com/java-decompiler/jd-gui.git
cd jd-gui
./gradlew build

It appears that jd-gui is using out-of-date libraries or something, as those libraries can no longer be found automatically from designated sources.

This error is happening because the build is trying to download dependencies from jcenter, which was deprecated and eventually shut down. The repository URL it's trying to use (https://jcenter.bintray.com) is no longer available.

Here's how to fix it:

1. Navigate to the root project directory of jd-gui
2. Open the file build.gradle in a text editor
3. Look for any repositories section that references jcenter()
4. Replace jcenter() with mavenCentral() or make sure mavenCentral() is included alongside it

You'll likely need to edit the repositories section to look something like this:

repositories {
    mavenCentral()
    // Remove or comment out jcenter() if present
}

If there are multiple build.gradle files, make this change in all of them. The main issue is that the build is trying to find the launch4j plugin from the now-defunct jcenter repository.

Alternatively, you could try a more recent version of the project if available, as newer commits might have already addressed this repository issue.

After making these changes, run the build command again:

./gradlew build

If you're on Windows and using the command prompt rather than Git Bash, you would use:

gradlew.bat build

This should help resolve the dependency resolution issue by pointing Gradle to the Maven Central repository instead of the defunct jcenter.

Hmm, it doesn't seem to work, looks like both packages that i had a error with, jd-core and the edu.sc, don't exist on both repo's. out of desperation, i had removed the edu.sc package and it worked... until it hit another error, and couldn't resolve jd-core.
