Overview<\/h3>\n

POM stands for Project Object Model. Maven POM file is an XML file. You can locate the file under the project root or base directory of the Maven project. It contains crucial information about the project and project configuration that are used by Maven to build the project.<\/p>\n

Structure<\/h3>\n

Every POM file has the following:
\nproject
\nmodelVersion
\ngroupID
\nartifactID
\nVersion<\/p>\n

 <\/p>\n

\"POM.xml<\/p>\n

Sample pom.xml<\/strong><\/h3>\n
<project xmlns=\"http:\/\/maven.apache.org\/POM\/4.0.0\" xmlns:xsi=\"http:\/\/www.w3.org\/2001\/XMLSchema-instance\"\r\n xsi:schemaLocation=\"http:\/\/maven.apache.org\/POM\/4.0.0 http:\/\/maven.apache.org\/maven-v4_0_0.xsd\">\r\n <modelVersion>4.0.0<\/modelVersion>\r\n <groupId>com.testingdocs.demo.webapp<\/groupId>\r\n <artifactId>simple-webapp<\/artifactId>\r\n <packaging>war<\/packaging>\r\n <version>1.0-SNAPSHOT<\/version>\r\n <name>simple-webapp Maven Webapp<\/name>\r\n <url>http:\/\/www.testingdocs.com<\/url>\r\n <dependencies>\r\n <dependency>\r\n <groupId>junit<\/groupId>\r\n <artifactId>junit<\/artifactId>\r\n <version>4.12<\/version>\r\n <scope>test<\/scope>\r\n <\/dependency>\r\n <\/dependencies>\r\n <build>\r\n <finalName>simple-webapp<\/finalName>\r\n <\/build>\r\n<\/project><\/pre>\n
