Jira 10 + React + WRM: Cannot load 'entrypoint' from wr-defs.xml in simple plugin

[DmSidorov]

Hi, I'm migrating plugins to Jira 10.3.0 using React 18 and bundling via Webpack 5 with atlassian-webresource-webpack-plugin.

I have a plugin with the following setup:

• Frontend entry: my-plugin (entry in webpack.config.js)

  const path = require('path');
  const MiniCssExtractPlugin = require('mini-css-extract-plugin');
  const WrmPlugin = require('atlassian-webresource-webpack-plugin');
  
  module.exports = {
      entry: {
          'my-plugin': './src/index.tsx',
      },
      output: {
          path: path.resolve(__dirname, '../backend/src/main/resources'),
          filename: 'js/[name].js',
          library: '[name]',
          libraryTarget: 'amd',
          publicPath: '',
      },
      resolve: {
          extensions: ['.tsx', '.ts', '.js'],
      },
      module: {
          rules: [
              {
                  test: /\.(ts|tsx)$/,
                  use: {
                      loader: 'babel-loader',
                      options: {
                          presets: [
                              '@babel/preset-env',
                              '@babel/preset-typescript',
                              '@babel/preset-react',
                          ],
                      },
                  },
                  exclude: /node_modules/,
              },
              {
                  test: /\.css$/i,
                  use: [MiniCssExtractPlugin.loader, 'css-loader'],
              },
          ],
      },
      externals: {
          react: 'jira/api/react-18',
          'react-dom': 'jira/api/react-dom-18',
      },
      optimization: {
          minimize: false,
          runtimeChunk: 'single'
      },
      plugins: [
          new WrmPlugin({
              pluginKey: 'com.example.my-jira-plugin-backend',
              xmlDescriptors: path.resolve(
                  __dirname,
                  '../backend/src/main/resources/META-INF/plugin-descriptors/wr-defs.xml'
              ),
              webResourceKey: 'entrypoint-my-plugin',
              providedDependencies: {
                  react: {
                      dependency: 'com.atlassian.plugins.jira-frontend-api:react-18',
                      import: { amd: 'jira/api/react-18', var: 'React' },
                  },
                  'react-dom': {
                      dependency: 'com.atlassian.plugins.jira-frontend-api:react-dom-18',
                      import: { amd: 'jira/api/react-dom-18', var: 'ReactDOM' },
                  },
              },
          }),
          new MiniCssExtractPlugin({
              filename: 'css/[name].css',
          }),
      ],
  };

• Generated resources: js/my-plugin.js, css/my-plugin.css (visible inside the JAR under /js and /css)

• Generated WR descriptor: wr-defs.xml is correctly placed under META-INF/plugin-descriptors/

  this is how it's generated:

In my atlasian-plugin.xml i connected my generated wr-defs.xml

<?xml version="1.0" encoding="UTF-8"?>
<atlassian-plugin key="com.example.my-jira-plugin-backend"
                  name="My Plugin"
                  plugins-version="2">

  <plugin-info>
    <description>My plugin description</description>
    <version>1.0.0</version>
    <vendor name="Example Company" url="https://example.com"/>
  </plugin-info>


  <web-resource-import key="wr-defs" file="META-INF/plugin-descriptors/wr-defs.xml"/>
  
  <servlet name="My React Page Servlet"
           key="my-react-page"
           class="com.example.plugin.MyReactPageServlet">
    <url-pattern>/my-react-page</url-pattern>
    <load-on-startup>1</load-on-startup>
  </servlet>
  
  <rest key="my-rest" path="/myplugin" version="1.0">
    <description>Provides REST endpoints for the plugin</description>
    <package>com.example.plugin.api</package>
  </rest>

</atlassian-plugin>

The assembly and installation of the plugin is successful, the only thing that confuses me is that there is a disabled mark opposite the wr-defs.

as a result, when I try to call my servlet, I get a 200 response from it and an error in the console:

Uncaught Error: undefined missing entrypoint-my-plugin.

Nothing else is downloaded in the network.

I've been struggling with the solution for several days now and would like to understand whether I'm thinking in the right direction or whether there is some other approach to writing jira 10 + react plugins without velosity and ajs.

HI @DmSidorov 

Welcome to the community.

Best is to ask this question in the Atlassian Developer Community
