Use eclipse to create a multi-module maven Project

Next I will explain how to use eclipse to create a multi-module maven project first to go to the eclipse workspace. my workspace directory here is G: \ Unionpay \ mavendemo1 and the total POMG is created: \ Unionpay \ mavendemo> mvn archetype: create-DgroupId = com. emailsys-DartifactId = platform: Create a maven project and modify the pom of the project. in the xml file, change the package type to pom <packaging> pom </packaging> and delete the src directory. 2. Create a sub-module under the directory of the main module (that is, under the platform directory just created ), create sub-module 1, such as emailsys: G: \ Unionpay \ mavendemo \ platform> mvn archetype: create-DgroupId = com. emailsys-Darti FactId = emailsys and then set pom. change the package type in xml to pom <packaging> war </packaging>. Note: This is a web project, therefore, when packaging, the war type is under the directory of the general module (that is, under the platform directory just created) and sub-module 2 is created, such as tablemodel: G: \ Unionpay \ mavendemo \ platform> mvn archetype: create-DgroupId = com. emailsys-DartifactId = tablemodel and then set pom. change the package type in xml to pom <packaging> jar </packaging>. Note: because this is a shared model, it is packaged into a jar package, other sub-web modules can use this public package. 3. In the root directory of the platform project, mvn eclipse: eclipse 4. import data through the eclipse import project. You can find two projects. Note: When installing the web Project, inside the structure must be maven web structure, that is to have webapp directory, WEB-INF directory, web. xml file. Otherwise, an error occurs during install!
