Error when including a Zig Library module

Help

Hi everyone! I’m encountering this frustrating build issue. Find below my build.zig and build.zig.zon, but the tl;dr is whenever I have the .curl member of the .dependencies in build.zig.zon, I encounter the following issue:

$ zig build run -- --host 127.0.0.1
/Users/axelpersinger/.cache/zig/p/curl-0.1.0-P4tT4ajAAABXSVzNUCk4dhXmeGpWYmqIzTlhS06-sL9V/build.zig:1:1: error: file exists in multiple modules

build.zig:

const std = @import("std");

pub fn build(b: *std.Build) void {
    const target = b.standardTargetOptions(.{});
    const optimize = b.standardOptimizeOption(.{});

    const exe = b.addExecutable(.{
        .name = "http-req",
        .root_source_file = b.path("src/main.zig"),
        .target = target,
        .optimize = optimize,
    });

    exe.root_module.addImport("curl", b.dependency("curl", .{}).module("curl"));
    exe.root_module.addImport("nexlog", b.dependency("nexlog", .{}).module("nexlog"));
    exe.root_module.addImport("simargs", b.dependency("zigcli", .{}).module("simargs"));
    exe.linkLibC();

    b.installArtifact(exe);

    const run_cmd = b.addRunArtifact(exe);
    run_cmd.step.dependOn(b.getInstallStep());
    if (b.args) |args| {
        run_cmd.addArgs(args);
    }

    const run_step = b.step("run", "Run the app");
    run_step.dependOn(&run_cmd.step);

    const exe_unit_tests = b.addTest(.{
        .root_source_file = b.path("src/main.zig"),
        .target = target,
        .optimize = optimize,
    });
    const run_exe_unit_tests = b.addRunArtifact(exe_unit_tests);

    const test_step = b.step("test", "Run unit tests");
    test_step.dependOn(&run_exe_unit_tests.step);
}

build.zig.zon:

.{
    .name = .curler,
    .version = "1.0.0",
    .fingerprint = 0x28ea6649c2db4109, // Changing this has security and trust implications.
    .minimum_zig_version = "0.14.0",
    .dependencies = .{
        .zigcli = .{
            .url = "https://github.com/jiacai2050/zigcli/archive/refs/tags/v0.2.0.zip",
            .hash = "zigcli-0.2.0-ORC7jMBzAgBv4oHEUgpASOmsx8O5iG_OeQy159MIRdYs",
        },
        .nexlog = .{

            .hash = "curl-0.1.0-P4tT4ajAAABXSVzNUCk4dhXmeGpWYmqIzTlhS06-sL9V",

zigcli is not updated to zig 0.14.0 and includes the same zig-curl library with the old hash.

Thank you! I appreciate it! I can’t wait for Zig error messages to get a little more clear :').

i know “can’t wait” is just an expression, but if you really can’t wait, i think folks who are just understanding a previously mystifying error message are uniquely positioned to offer suggestions for improvement in the form of a PR :smiling_face:

v0.2.1 has been released and supports the new hash format.
