Normally, when working with the Node.js project, we usually ignore the node_modules directory, which is used to store Node.js dependencies, when committed to source code management systems such as Git, SVN because it’s not necessary. You can use the “npm install” command to install dependencies… Read More
Imagine you are building an application with many different projects, for each project you need to declare to use some dependencies with the fixed versions. Some projects need to use the same dependencies and of course the same version. How do we feel when we… Read More
In the previous tutorial, I showed you some of the basic configurations in the Apache Maven settings.xml file with <localRepository />, <interactiveMode />, <offline />, <pluginGroups />, <proxies /> tags. In this tutorial, we will learn more about some of the more important parts of… Read More
The settings.xml file is the Apache Maven configuration file, which defines how Apache Maven will execute to handle dependencies when we use these dependencies in Maven projects. Instead of defining the configuration information in the pom.xml file for each Maven project, we can use the… Read More
