在maven中，将文件夹添加为源文件夹，但不要将其包含在源jar中

I have a web project identity which depends on two jar authentication and authorization. In project identity, I am generating xsd using jaxb2-maven-plugin for authentication, authorization and identity sources. As the plugin jaxb2-maven-plugin, works only on sources exists in the maven source path, I am downloading sources for authentication and authorization in a folder target/schema, add this folder target/schema as a maven source folder and then running jaxb2-maven-plugin to generate xsd. Now, when I build source jar for identity, it also includes sources for authentication and authorization which I dont want.

Maven Source plugin has option for excluding selected files from created source JAR.

exclude

List of files to exclude. Specified as fileset patterns which are relative to the input directory whose contents is being packaged into the JAR.
