I have both build automation tools (maven, gradle) in my project. Of course, I can switch between them, but I would like to completely remove maven from the project and use only gradle.
How can I remove maven from the project? Do I only need to remove maven related files?

It may be just that I have a general misunderstanding how gradle build works, but it feels to me that I can not build a maven file inside of a gradle build. Since gradle uses the gradle.build file, and maven uses a pom.xml, it does not seem as though I can do this. I have multiple maven projects that I would like to wrap up with a gradle wrapper. I can not find ANYTHING on whether this is even possible.
Both Maven and Gradle are build tools and you should only use one of them for a given project.
If you have existing Maven projects and like the functionality provided by the Gradle wrapper, there is a similar wrapper for Maven (note that this is currently a third-party plugin but they plan to include it in the upcoming release 3.7 of Maven).
Alternatively you could convert your projects entirely to Gradle.
I have several Gradle library projects and main Ant spring web-app project (historically). I'd like to replace Ant with Maven for main project while keeping existing Gradle projects nature.
Is it possible to refer local Gradle projects from pom.xml as local dependencies of Maven project?
Search readily gives me the opposite - "how to refer maven projects from gradle builds", but not my case.
Gradle always builds locally build/libs (or distributions); the only easy way to share the build dependencies between completely different projects is 'as maven repository dependencies'
in your case the options are
Work Local Builds only
add the maven plugin to the gradle builds - do local install
and refer them in the maven build locally.
Build Anywhere
Your Gradle builds publish artefacts to your local nexus
and you refer them properly in your dependencies

Gradle by default does not have 'maven install'; it can be added using the maven plugin see - https://docs.gradle.org/current/userguide/maven_plugin.html#header.
I am trying to build a Maven plugin using Eclipse. I need it to be in a project called Utilities (contains some other utility tools), i.e. I do not want the plugin to be an Eclipse project all by itself.
The <packaging> tag for Utilities project in its POM is jar, while technically a maven plugin needs to be packaged as a maven-plugin. Is there any way to get around this? Or must I build the Maven plugin as a separate project?
What is the purpose to use Maven Tycho plugins. I read here tycho is used for building eclipse plugins and OSGI bundle.
Questions:- Can not we build eclipse plugins and OSGI bundle just by using the plain old maven POM.xml file[by not using tycho plugin].
What does maven need tycho plugin to help it build eclipse plugin and OSGI bundles?
Why should we use Maven tycho plugin to build eclipse plugins and OSGI bundles?
When using maven (or other command line build tools) manifest.mf) in combination with Eclipse (or another IDE) the classpath ends up being written down twice - once in the pom.xml and once in the Eclipse .classpath (or, for OSGi, in the target platform and manifest.mf). This violates the DRY principle.
There are various solutions to this problem. One is something like m2e, where you use the pom.xml to generate the Eclipse .classpath. Alternatively, you can go in the other direction and start by getting things compiling in Eclipse, and then use a maven plugin to convert that Eclipse setup to a maven build. This is what Tycho does, with the extra wrinkle that it works from a PDE manifest + target platform rather than directly from the .classpath.
Maven doesn't have a built-in packaging type for OSGi bundles and/or Eclipse plugins. So unless you want to use the jar packaging type and manually add OSGi specifics, you need a Maven plug-in to help you with this.
Tycho is one of the plugins that add support for building OSGi bundles.
I have developed an Eclipse plugin project. Now I need to convert it to a Maven Project so that the dependencies etc can be handled using pom.xml.
Is there a way to convert the plugin project to a Maven project?
Right click on your project -> Configure -> Convert to Maven Project
you need eclipse m2e to do this
btw. if you dont know: if you want to use maven with eclipse plugins, you will need tycho too. see eclipse tycho
