java - Web 脚本 groovy - Alfresco

Question

我正在尝试用 groovy 制作一个 Web 脚本并在 Alfresco 上运行该 Web 脚本。但是，我不知道该怎么做。我阅读了教程，但还没有得出任何结论...... 有人知道在 groovy 中运行 Web 脚本的所有步骤吗？我需要哪些文件？ 我的想法是在 Alfresco 上集成一个 groovy 应用程序。

例如，我正在尝试测试以下 Web 脚本之一:https://github.com/pmonks/alfresco-groovy-webscripts

但我收到错误:

我也尝试了 Alfresco 示例中已有的 Web 脚本，但出现错误，例如:

The Web Script /alfresco/s/default/surfbug has responded with a status of 500 - Internal Error.

对我来说，这看起来完全是一个 Maven 问题。该异常指出无法从任何存储库下载 Artifact 。这意味着您对本地存储库或任何默认或配置的远程存储库中都找不到的东西有依赖关系。

缺少的依赖项被声明为org.alfresco.extension:alfresco-groovy-webscripts-parent:pom:1.3。要使其正常工作，此 Artifact 需要位于您的本地存储库中。我在公共(public)远程存储库中找不到对此的任何引用，因此您可能需要从源代码构建它。

您在问题中提供的链接适用于 github 项目，其 pom.xml 文件中包含以下代码:

  <groupId>org.alfresco.extension</groupId>
  <artifactId>alfresco-groovy-webscripts-parent</artifactId>
  <packaging>pom</packaging>
  <version>1.4-SNAPSHOT</version>

请注意，groupId 和 artifactId 与您缺少的依赖项匹配，但版本不同。如果您已使用 mvn install 安装了此示例，则此依赖项的版本 1.4-SNAPSHOT 应该已位于您的本地存储库中。您可以在 pom 文件中搜索对 alfresco-groovy-webscripts-parent v1.3 的依赖，并将其更改为 1.4-SNAPSHOT，然后重试。
