在 Maven 中，添加一个文件夹作为源文件夹，但不要将其包含在源 jar 中

Question

我有一个用例，我需要使用 maven-buildHelper 插件将文件夹 target/schemas 包含为源文件夹。我正在为这个项目发起一场战争。创建源 jar 时，目标/模式的内容也存在于其中。我不想将目标/模式的内容添加到我的源 jar 中。如何实现？

我有一个 web 项目身份，它依赖于两个 jar 身份验证和授权。在项目身份中，我使用 jaxb2-maven-plugin 生成 xsd 用于身份验证、授权和身份源。作为插件 jaxb2-maven-plugin，仅适用于 maven 源路径中存在的源，我在文件夹 target/schema 中下载用于身份验证和授权的源，将此文件夹 target/schema 添加为 maven 源文件夹，然后运行 ​​jaxb2 -maven-plugin 生成 xsd。现在，当我为身份构建源 jar 时，它还包括我不想要的身份验证和授权源。

Answer 1

Maven Source plugin 具有从创建的源 JAR 中排除选定文件的选项。

exclude

要排除的文件列表。指定为文件集模式，这些模式与将其内容打包到 JAR 中的输入目录相关。
