Alright, so I'm trying to compile my mod and I'm getting the titles error. The mod works fine, it just can't build. I tried deleting the build directory, but it didn't work. This link also provides an error from another person, except they fixed it buy reinstalling forge.

https://stackoverflow.com/questions/55997879/issue-with-compiling-mod-at-reobfjar-java-util-zip-zipexception-duplicate-entr

Unfortunately, I'm not sure how to do this.

Any help would be appreciated,

thanks.

Run the build command with the "--stacktrace" option and provide us with the log as well as your build.gradle.

When i put --stacktrace, it give me this:

 

Unable to start the daemon process.
This problem might be caused by incorrect configuration of the daemon.
For example, an unrecognized jvm option is used.
Please refer to the user guide chapter on the daemon at https://docs.gradle.org/4.8.1/userguide/gradle_daemon.html
Please read the following process output to find out more:
-----------------------
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.
Unrecognized option: --stacktrace

-----------------------
Check the JVM arguments defined for the gradle process in:
 - gradle.properties in project root directory

 

Ok, so i put it in the arguments section and the command works, but where is the log?

What exactly did you type?

I got it working by putting it in the arguments section (Not JVM), but where is the log directory?

It would be in the command line interface. I don't believe it makes an actual file, but if it does someone will surely correct me.

I don't see it in the build output, and also I'm using intellij to build it, not cmd.

Ok, so i did it in the CMD line and heres what i got:

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':reobfJar'.
> java.util.zip.ZipException: duplicate entry: assets/moremachines/lang/en_us.lang

* Try:
Run with --info or --debug option to get more log output. Run with --scan to get full insights.

* Exception is:

Seems like there is a duplicate entry for your lang file somewhere. Potentially in your build.gradle file.

Here is my build.gradle:

buildscript {
    repositories {
        jcenter()
        maven { url = "https://files.minecraftforge.net/maven" }
    }
    dependencies {
        classpath 'net.minecraftforge.gradle:ForgeGradle:2.3-SNAPSHOT'
    }
}
apply plugin: 'net.minecraftforge.gradle.forge'
//Only edit below this line, the above code adds and enables the necessary things for Forge to be setup.


version = "1.0"
group = "com.moremachines.moremachines" // http://maven.apache.org/guides/mini/guide-naming-conventions.html
archivesBaseName = "moremachines"

sourceCompatibility = targetCompatibility = '1.8' // Need this here so eclipse task generates correctly.
compileJava {
    sourceCompatibility = targetCompatibility = '1.8'
}

minecraft {
    version = "1.12.2-14.23.5.2836"
    runDir = "run"

    // the mappings can be changed at any time, and must be in the following format.
    // snapshot_YYYYMMDD   snapshot are built nightly.
    // stable_#            stables are built at the discretion of the MCP team.
    // Use non-default mappings at your own risk. they may not always work.
    // simply re-run your setup task after changing the mappings to update your workspace.
    mappings = "stable_39"
    // makeObfSourceJar = false // an Srg named sources jar is made by default. uncomment this to disable.
}

dependencies {
    // you may put jars on which you depend on in ./libs
    // or you may define them like so..
    //compile "some.group:artifact:version:classifier"
    //compile "some.group:artifact:version"

    // real examples
    //compile 'com.mod-buildcraft:buildcraft:6.0.8:dev'  // adds buildcraft to the dev env
    //compile 'com.googlecode.efficient-java-matrix-library:ejml:0.24' // adds ejml to the dev env

    // the 'provided' configuration is for optional dependencies that exist at compile-time but might not at runtime.
    //provided 'com.mod-buildcraft:buildcraft:6.0.8:dev'

    // the deobf configurations:  'deobfCompile' and 'deobfProvided' are the same as the normal compile and provided,
    // except that these dependencies get remapped to your current MCP mappings
    //deobfCompile 'com.mod-buildcraft:buildcraft:6.0.8:dev'

    inputs.property "version", project.version
    inputs.property "mcversion", project.minecraft.version

    // replace stuff in mcmod.info, nothing else
    from(sourceSets.main.resources.srcDirs) {
        include 'mcmod.info'

        // replace version and mcversion
        expand 'version':project.version, 'mcversion':project.minecraft.version
    }

    // copy everything else except the mcmod.info

He got it to work through reinstalling forge, but I'm not sure how to do that.

I'm using Intellij btw.

Bump.

Bump 2.

Does anybody have a solution?

I have the same probleme, Did you find a solution without reinstalling?
