我必须为 nuxeo 创建一个自定义插件。为了动手，我得到了cloudbinarymanager的源代码，其中包含不同存储连接器的源代码。
我按照文档中编写的步骤进行操作。从终端，我将目录更改为上面提到的项目并运行命令 -
nuxeo bootstrap package
这会在项目中创建一个模块，运行命令后会在其中创建附加 zip -
mvn package
要安装此附加组件，请使用以下命令 -
./nuxeoctl mp-install path/to/add/on/zip/file
它已成功安装，但服务器未启动。
该命令./nuxeoctl start尝试启动服务器一段时间，但随后放弃。
我在服务器日志中看不到任何错误，但我在localhost.log文件中看到以下内容：

通常，当我尝试在未安装此自定义插件的情况下运行服务器时，我不会在 localhost 日志中收到此类错误。
