Maven管理的jar没有发布到WEB-INFlib下的解决方案.doc

Maven管理的jar没有发布到WEB-INF/lib下的解决方案标准web工程在eclipse中利用m2eclipse插件添加依赖管理后，在部署过程中没有将依赖的jar包自动拷贝到/WEB-INF/lib中。参考了一些朋友的做法手动执行javaview plaincopy1. mvndependency:copy-dependencies-DoutputDirectory=src/main/webapp/WEB-INF/lib-DincludeScope=runtime命令将jar包拷贝到/WEB-INF/lib目录下。这种做法固然可以，但是也会带来一些不便。1、需要手动执行命令。2、不能时时更新。 以下列出网上查找到的解决方法，m2eclipse plugin方式已验证通过。通过验证eclipse版本：eclipse-jee-helios-SR2-win32m2eclipse插件地址：/sites/m2e标准web工程通过m2eclipse添加依赖管理步骤：1、“Maven ” “Enable dependency Management“2、Web Deployment Assembly中添加maven dependencies步骤如下图：工程 - 右键 - preferences.classpath文件中会有修改xhtmlview plaincopy1. 为xhtmlview plaincopy1. 2. 3. 4. 5. (执行“Maven ” “Update Project Configuration “未生效，故手动添加。必须deploy时候才会拷贝jar包到lib目录下，而非在更新maven依赖时候拷贝jar包。)以下为原文内容：Eclipse : Web Deployment Assembly & Maven dependencies issuePublished: September 3, 2010 , Updated: September 3, 2010 , Author: mkyongprintProblemIn Eclipse 3.5 or early version, in order to deployed the Maven dependencies to the correct “/WEB-INF/lib” folder, you have to configure the dependencies via “Java EE Module Dependencies”, and the updated “.classpath” file will look like following :File : “.classpath”, by Java EE Module Dependenciesxhtmlview plaincopy1. .2. 4. 5. 6. 7. 8. .Since Eclipse 3.6, the “Java EE Module Dependencies” is replaced by “Web Deployment Assembly”, but you can do the same via the “Referenced Projects Classpath Entries”, however, it will update the “.classpath” file as following :File : “.classpath”, by Web Deployment Assemblyxhtmlview plaincopy1. .2. 4. 5. 6. 7. 8. .Sadly, the default(value=”./”)makes all the Mavens dependencies failed to deploy.SolutionNot a big issue, you still can modify the(value=”./”)to(value=”/WEB-INF/lib”)manually, but it will get override every time you run a Maven build. No worry, there are still have two solutions :1.
