Java – Maven version cannot be changed in the eclipse ide

There was no MVN package inside eclipse, but after success in the terminal, I realized that eclipse was running Maven 3.3 3. Terminal operation 9. I try to succeed through all obvious accounts, reconfigure eclipse by accessing eclipse – > preferences – > maven – > install and point to my 3.3 9 folders I restarted eclipse and tried again, but nothing was available In addition, when you try to build, you do not confirm the connection to POM Changes to XML files I inserted inappropriate slashes and other characters. I can only generate this error:

Error assembling War: Web. Is required XML attribute (pre-existing WEB-INF / Web. XML if executed in update mode)

I modified my POM file according to this recommendation, but as I said, Maven didn't recognize the changes to POM, and I couldn't run MVN – version to generate 3.3 9. I attached my POM below xml

Solution

Try setting up the runtime configuration, or check to see if you already have one

In eclipse, right-click the project – > run as - > run configuration Find the M2 Maven build section on the left If there is one under the project name, edit it, otherwise create one There is a drop-down list at the bottom of the dialog box that allows you to select the Maven configuration to run:

This gives me the following output:
