What is the difference between compile and install in Maven?

In Maven, the difference between compile and install phases is significant. When you use the compile phase, Maven compiles the source code of your project and resolves dependencies specified in the pom.xml file. However, the compiled code is not packaged or installed anywhere.

On the other hand, the install phase in Maven compiles the source code, resolves dependencies, packages the compiled code (e.g., JAR file), and installs it in the local Maven repository. This allows other projects to use the artifact as a dependency.

While the compile phase is mainly concerned with checking the code and dependencies, the install phase goes a step further by packaging and making the artifact available for other projects to use.
