Jenkins uses different version of Maven than cmd - maven

First I installed Maven version 3.0.5 on our build system and then I upgraded it to 3.6.0 following this guide https://linuxize.com/post/how-to-install-apache-maven-on-centos-7/ . Using the cmdline on the system executing:
mvn -v
I always get 3.6.0 as the version. But when executing the same command in a Jenkins job I get 3.0.5 . So somewhere it looks like it still refers to the older version. But I have no clue where. Any ideas how to check this?

The version you see in the shell depends on your PATH variable.
Jenkins can handle multiple installations of maven.
To configure it:
Open the Jenkins dashboard.
Go to Manage Jenkins.
Go to Global Tool Configuration
Go to the Maven section and click Maven installations
When adding a new installation, you have 2 options:
install a selected version automatically
use existing installation on your system
Then, when configuring a project in jenkins, you can select one of the configured installations.
For Maven Project under Build / Maven Version
For Freestyle project under Build Steps / Build / Invoke top level maven targets / Maven Version

Gradle cannot update successfully from v6.5.1 to v7.0.0

I am trying to update my local gradle(out of ide) from 6.5.1 to 7.0.0.
I try two commands from gradle website and network in cmd and path is the root of one of my project(there are gradlew.bat and gradlew files):
gradle wrapper --gradle-version=7.0 --distribution-type=all
gradlew wrapper --gradle-version=7.0 --distribution-type all
And, i try those commands to check the version
gradle -v
gradlew -v
The gradlew updates sucessfully. It prints version 7.0.0.
However, the version of gradle is still in v6.5.1.
How can I update it without download the v7.0.0 packet and cover the files in disk(I am worrying about that i should download all of my packages again in new gradle)?
ps: the gradle is locating in D:\gradle in my disk and java environment is openJDK 15
Thanks agains
I had the same problem and, in my case, the problem was a running gradle demon using the previous version. Check running demons with:
gradle --status
Stop the demons with
gradle --stop
Also I restarted the console/terminal.
You cannot update your gradle standalone version without downloading it, and with gradle wrapper you cannot upgrade your gradle installation, it always works on your current project folder (command gradlew) only. To upgrade a standalone gradle installation (command gradle without the wrapper prefix w), you have to manually download the binaries, include the new bin directory in your PATH environment as described in the manual on the gradle homepage, or use a package manager like sdk man, chocolatey, brew etc.
If you are using the gradle wrapper gradlew for your builds, it works completely independent from your gradle installation.

Not sure whether maven is installed or not

I use intellij for development purpose on my mac. It has support of maven in it. But when I thought of running mvn command via terminal, it was not able to identify and maven on my system. Why?
Maven of your IDE (embedded maven) & Maven of your operating system are Different by default.
If you don't install Maven on your Op.System then you can't use Maven command line in your terminal.
If you have installed maven on your Op.System so probably you fall with 2 different maven version (IDE Embedded maven and Op.system maven)
To evoid this problem install maven on your Op.system (dont forget to configure env variable M2_HOME) and configure your IDE to use this installation of Maven.

Install m2e in eclipse without install maven in system

I recently try to use maven in my eclipse project. In maven official website there are several step that I must to accomplish to configure maven side by side with eclipse. But I know there is a m2eclipse plugins if I need to use maven. But I don't know if I can use this plugins with maven installed in system or not.
So can I use this plugins without maven been installed in system or not ?
The m2e plugin brings a copy of Maven 3.0.4 and installs it inside of Eclipse so the plugin can use it. This is enough to build Maven projects inside of Eclipse. No external installation is needed.
You must start Eclipse with a JDK, though. A JRE isn't enough. If you're unsure: Look for the file lib/tools.jar. When it's there: You're good.
This copy isn't accessible from the command line. If you want to build from the command line as well or if you need a newer version of Maven than 3.0, you need to install Maven and configure the plugin accordingly.

Which version of Maven does IntelliJ use and how do I find out

I'm using IntelliJ with both Maven plugins enabled. Where is maven installed on my computer though, and how do I find out which version IntelliJ uses?
You can find bundled maven version in Project Settings -> Build execution and deployment -> Build Tools -> Maven, under Maven home directory.
Go to File -> Settings and use the search bar to find maven settings.
There you can find the maven version (usually against the field "Maven home directory" ).
By default IntelliJ uses the Maven defined by your M2_HOME system variable although you can change this in the preferences.
To find where it is installed run this on the command line:
mvn -version
I'm also using IntelliJ with both Maven plugins enabled.
Check which version IntelliJ is currently using:
Open Project Settings and search 'Maven' or Go to Project Settings -> Build, execution, deployment -> Build Tools -> Maven
For Mac Users:
Open Preferences and search 'Maven' or Go to Preferences -> Build, execution, deployment -> Build Tools -> Maven
You can see both the current version that IntelliJ is using and the bundled maven version.
Check where maven is installed:
Use the following command in Terminal:
mvn -v or mvn -version
It shows you the installed version and location like below if mvn is installed, otherwise you'll get command not found error.

IntelliJ cannot find Maven M2_HOME environment variable

I'm trying to make my first step with Maven system. But I cannot understand if I should install it separately or if it comes built-in with IntelliJ 13 Community Edition? My system is Windows 7.
Maven does not come bundled with Intellij. You need to install the version of Maven you'd like to use on your computer.
Intellij has a Maven plugin, which requires that you either set M2_HOME or supply it with the location of your Maven install.
First you should it install it separately cause you will need it on command line. Furthermore it's best to understand maven on command line first and than make the integration step into Maven with an IDE of your choice.
