如何用maven只构建java文件？(How to build only java files with maven?)

我的项目层次结构如下所示

myProject--->POM.xml myProject--->src--->main--->java---> java files under different sub directories myProject--->src--->main--->resources---> non java files under different sub directories myProject--->src--->main--->webApp---> non java files under different sub directories

我想构建项目，以便它只构建java文件，并在最终的jar文件中只包含相应的类文件

这是我在pom.xml中的相关代码，但它没有找到任何要编译的java文件。我不确定我在这里缺少什么？

<build> <pluginManagement> <plugins> <plugin> <artifactId>maven-jar-plugin</artifactId> <configuration> <verbose>true</verbose> <includes> <include>**/*.java</include> </includes> </configuration> </plugin> </plugins> </pluginManagement> </build>

更新： -我收到信息消息为No sources to compile但子目录中有java文件

i have my project hierarchy like below

myProject--->POM.xml myProject--->src--->main--->java---> java files under different sub directories myProject--->src--->main--->resources---> non java files under different sub directories myProject--->src--->main--->webApp---> non java files under different sub directories

i want to build the project so that it builds only java files and only include the corresponding class files in final jar file

Here is my relevant code from pom.xml but it does not find any java files to compile. I am not sure what i am missing here?

<build> <pluginManagement> <plugins> <plugin> <artifactId>maven-jar-plugin</artifactId> <configuration> <verbose>true</verbose> <includes> <include>**/*.java</include> </includes> </configuration> </plugin> </plugins> </pluginManagement> </build>

UPDATE:- I get info message as No sources to compile but there are java file in subdirectories
