maven 构建成功，虽然 npm 部署有错误

Question

我尝试通过 exec-maven-plugin 部署 npm module。我使用 https://github.com/arkanjoms/nexus-npm 中的 nexus-npm 工具。

在我的 pom 中，我是这样执行的：

<execution>
  <id>Deploy module via nexus-npm</id>
  <goals>
    <goal>exec</goal>
  </goals>
  <phase>deploy</phase>
  <configuration>
    <workingDirectory>${project.build.directory}/npm</workingDirectory>
    <executable>nexus-npm</executable>
    <arguments>
      <argument>deploy</argument>
    </arguments>
    <environmentVariables>
      <HOME>${project.build.directory}/npm</HOME>
    </environmentVariables>
  </configuration>
</execution>

一切正常，但是当部署失败时，maven 构建仍然标记为成功。当部署不成功时，如何告诉maven构建应该失败？

npm ERR! publish Failed PUT 400
npm ERR! code E400

澄清一下，我知道部署失败的原因，这不是我的问题。我只想知道如何在部署出错时将maven构建标记为失败

Answer 1

arkanjoms/nexus-npm plugin uses app/publish-snapshot.js

publishSnapshot: function (snapshotRepository) {
    log.info('publish snapshot => ' + snapshotRepository);
    shell.exec('npm publish --registry=' + snapshotRepository);
},

这意味着 shelljs/shelljs exec 命令不检查其 return 代码。

应该是：

if (shell.exec('npm publish --registry=' + snapshotRepository).code !== 0) {
  shell.echo('Error: npm publish snapshot failed');
  shell.exit(1);
}

同样，发布快照步骤的调用不会在 app/commands.js

中出现任何错误

    deploy: function () {
        this.verify();
        this.backup();
        if (commander.release) {
            tag.createTag(this.appConfig, this.config.tag, this.message);
            release.publishRelease(this.appConfig.packageJson.distributionManagement.releaseRegistry);
            release.updatePkgVersion(this.appConfig, this.message);
            rollback.clean();
        } else {
            snapshot.addDateToVersion(this.appConfig);
            snapshot.publishSnapshot(this.appConfig.packageJson.distributionManagement.snapshotRegistry);
            rollback.rollback();
        }
    },

就目前的插件实现而言，当部署出现错误时，将 maven 构建标记为失败并不容易。

maven 构建成功，虽然 npm 部署有错误

Maven build is successful although npm deployment has an error

maven

exec-maven-plugin
