我使用 jHipster 4.9.0 生成单一应用程序，当我运行 mvn -Pprod软件包时，构建失败并出现以下错误。
[ERROR] Failed to execute goal com.github.eirslett:frontend-maven-plugin:1.6:yarn (webpack build prod) on project itob-p: Failed to run task: 'yarn run webpack:prod' failed. org.apache.commons.exec.ExecuteException: Process exited with an error: 1 (Exit value: 1) -> [Help 1]
我还重新安装了包含npm软件包5.3.0的Nodejs，并删除了文件夹node_modules并在生成的文件夹上重新安装npm但没有成功。如果我做错了，我就陷入困境并无法确定问题，请指出。
到目前为止做了什么：
1）操作系统= Windows 7 64位
2）生成非政治应用的源代码[yo jhipster]
3）数据库postgrase
4）OAuth2
5）mvn -Pprod包
6）在[Dev]模式下成功部署Pivotal Cloud Foundry
请注意，在为生产进行构建时会出现此问题。
这是此命令的完整堆栈。 我无法识别并理解这个问题。请帮助我，如果您有任何建议，请分享 这是完整的错误堆栈。

只需运行yarn，并在需要时对其进行更新。然后再试一次。它对我有用。
