安装自定义程序包后Nuxeo服务器无法启动

标签： java maven nuxeo linkageerror

我必须为nuxeo创建一个自定义插件。为了获得一些实际操作，我获得了cloudbinarymanager的源代码，其中包含适用于不同存储连接器的源代码。

我遵循了docs中编写的步骤。从终端，我将目录更改为上述项目，并运行命令-

nuxeo bootstrap package

这将在项目内部创建一个模块，在运行命令后，将在其中创建附加的zip-

mvn package

要使用命令安装此加载项， 

./nuxeoctl mp-install path/to/add/on/zip/file

它已成功安装，但服务器无法启动。

命令./nuxeoctl start尝试启动服务器一段时间，但随后放弃了。

我在服务器日志中没有看到任何错误，但是在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，在本地主机日志中不会出现此类错误。

1 个答案:

答案 0 :(得分：0)

您的自定义插件似乎依赖于 slf4j 。

如果它是直接依赖项（您直接在 pom.xml 中拥有它），则将其移至提供的范围内：

<dependency>
  <groupId>org.slf4j</groupId>
  <artifactId>slf4j-simple</artifactId>
  <version>1.7.21</version>
  <scope>provided</scope>
</dependency>

如果它是一个临时依赖项（另一个工件将其作为依赖项），则在 org.slf4j 包上为其添加排除项：

<dependency>
  <groupId>artifact.with.transient</groupId>
  <artifactId>dependency-on-slf4j</artifactId>
  <version>1.2.3</version>
  <exclusions>
    <exclusion>
      <groupId>org.slf4j</groupId>
      <artifactId>*</artifactId>
    </exclusion>
  </exclusions>
</dependency>
