multiple marketplace package manifests found

Error message

multiple marketplace package manifests found

What it means

ExtractLocalPackage scans the extracted package root for exactly one of plugin.json, theme.json, icon.json, template.json, or widget.json. If a regular file matching two or more of these manifest names exists in the same root, it cannot decide the package type and throws this error. The temp extraction is cleaned up before returning.

Solutions

1. Remove all manifest files from the package root except the one matching the intended package type
2. Repackage the zip with only one manifest (plugin.json XOR theme.json XOR icon.json XOR template.json XOR widget.json)
3. Check .gitignore/build scripts so other projects' manifests are not copied into the output

Example fix

// before: package root contains plugin.json AND theme.json
// after:
my-plugin/
  plugin.json
  index.js
  ...

const allowed = ["plugin.json","theme.json","icon.json","template.json","widget.json"];
const found = allowed.filter(f => fs.existsSync(path.join(pkgRoot, f)) && fs.statSync(path.join(pkgRoot, f)).isFile());
if (found.length !== 1) throw new Error("package must contain exactly one manifest, found: " + found.join(","));

When it happens

Trigger: Calling ExtractLocalPackage (or InstallLocalBazaarPackage) on a zip whose package root contains e.g. both plugin.json and theme.json as regular files.

Common situations: A developer merges several package types into one directory before packaging; a zip accidentally bundles manifest files left over from another project; CI copies multiple manifests into the build output.

Understand the failure class

Background: Conflicting config options: "cannot be used together" — configuration validation errors across open-source libraries — this error's family across 162 libraries.
