Error: M2_HOME is set to an invalid directory

Question

I got this error

Error: M2_HOME is set to an invalid directory.
M2_HOME = "C:/Users/joanet/.m2/repository"
Please set the M2_HOME variable in your environment to match the
location of the Maven installation

but C:/Users/joanet/.m2/repository is a valid directory !

M2_HOME should address to apache-maven home directory. Example: `C:\apache-maven-3.3.3` — troig, Oct 29 '15 at 14:52
Remove M2_HOME only add the bin folder of the distribution into your path...not more is neccessary. — khmarbaise, Oct 29 '15 at 14:54

Yes, your folder is valid, but this is not the folder you want to point to.

I think it should point actually where the error messages says to you, to your maven installation folder (something like this)

C:\development\maven\apache-maven-3.1.0

You are currently pointing to your local repository, something which is usually configured in the settings.xml of maven (in the conf folder of the previous url route).

Such issue appears also, if you have 2 or more mavens installed. Try to delete old versions to have only latest.

Check the System Variable M2_HOME and PATH values set in different maven installation locations.

If your java version is 8 you can remove "MAVEN_OPTS : -Xms256m - XMX512m" environmental variable and check "mvn -v". because java 8 does not support for the above config.

This happened to me when I tried to upgrade to new Maven version.
Below are the steps you should follow when setting up Maven on Windows.
If something is missing, the above error will trigger (most probably the 2nd or 3rd step may be missing for mentioned error).

Step 1:

First, download(Apache Maven download link: https://maven.apache.org) and extract it to C:\Program Files

Step 2:
