E.g.:
<parent> <groupId>mycompany.trade.com</groupId> <artifactId>mycompany.trade.</artifactId> <version>1.1.1.0-SNAPSHOT</version> </parent> Does it mean that Maven will search for parent pom? If yes, where, in which order? May be in folder up 1 level? Or in local repository or in repo?

Maven Basics. Maven parent POM (or super POM) is used to structure the project to avoid redundancies or duplicate configurations using inheritance between pom files. It helps in easy maintenance in long term.
A POM can be a parent POM and it will be inherited to all child POM. So all the dependencies which has been set in parent POM need not to set in child POM. But if any dependency jar has been configured in parent and child POM both with different version then the child POM�s dependency version is takes priority.
Spring Boot Starter Parent is a starter project that provides the default configuration for spring-based applications. It is added as a parent in the pom. xml file. The spring-boot-starter-parent defines spring-boot-dependencies as its parent.
All Spring Boot projects use spring-boot-starter-parent as a parent in pom. xml file. Configuration: It allows us to maintain consistency of Java Version and other related properties. Dependency Management: It controls the versions of dependencies to avoid conflict.
Yes, maven reads the parent POM from your local repository (or proxies like nexus) and creates an 'effective POM' by merging the information from parent and module POM.

One reason to use a parent is that you have a central place to store information about versions of artifacts, compiler-settings etc. that should be used in all modules.

The common dependencies,Properties,constants etc can be definded in central parent project pom.xml
The main important thing is the parent project cannot be distributed and it looks quite similar to a regular "pom.xml" except that it also has a packaging tag
<groupId>com.company.demo</groupId> <artifactId>MavenInheritance</artifactId> <version>0.0.1-SNAPSHOT</version> <packaging>pom</packaging> The child now able to inherit this using
<parent> <groupId>com.company.demo</groupId> <artifactId>MavenInheritance</artifactId> <version>0.0.1-SNAPSHOT</version> </parent> If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
