如何得到 Maven 项目窗口在 Intellij 14 | 更新: 无法看到右侧的“标签栏”与 Maven 项目

You can find the Maven Projects pane by going to Help > Find Action or press Ctrl + Shift + A and type in "Maven Projects". However I can't see it anywhere in the elaborate menu's.

First, make sure you have enabled maven plugin in

File → Settings → Plugins → Maven Integration

If so and still the tool window is hidden then

go to View → Tool Windows → Maven Projects to open it.

For those stuck with this issue, enable View -> Tool Buttons.

It's a bit late, but I had the same problem with missing sidebars. At least in IDEA 2017.3 there is an icon on the bottom left of the screen that toggles the sidebars. That's how I got it back.

Weird but this works at times:

Disable File → Settings → Plugins → Maven Integration first and restart Intellij. Then re-enable it back and restart - this might fix the issue.

Enable maven plugin first in

File → Settings → Plugins → Maven

Also, make sure you enable Tool Buttons in

View → Tool Buttons

If View → Tool Windows → Maven Projects doesnt work that means tools button is deselected

go to View -> Tool Buttons and select it . You should be able to Maven window now

I had similar problem until I right-clicked the option in POM "Add as Maven Project".

Notice: IDEA 2019.2 and I couldn't even find Maven in "Tool Windows" of the (existing) project before it.

Very simple. NO PLUGINS.

Maven comes by default so you should press two times the shift key and write "maven".

Then import the maven project ".pom" and the bar cames automatically after selecting the pom.

I had the same problem with a maven project, the tab wasn't showing up and even in the View->Tool windows menu, there was no maven item.
After searching the internet i could not find a solution but then i looked in Intellij idea
and noticed a Even Log showing a number in a red circle, i clicked it and then read an error message:

Non-managed pom.xml file found:
Add as Maven Project

check out solution proposed by invzbl3, It might help.

Check if at the bottom line of Intellij, it says "non-managed pom files found."

You can then "Add as a Maven Project"

The question asked is how to show the sidebar, not show the Maven Plugin. On my version of Intellij this is enabled with the following:

View -> Appearance -> Tool Window Bars

Make sure your Maven plugin is enabled as well. In my case, it was disabled for an unknown reason. To enable it: Settings → Plugins → Installed (Scroll down to Bundled section)

If you not use Maven, can delete it.

open ProjectName.iml file in root of project of module.

then remove "org.jetbrains.idea.maven.project.MavenProjectsManager.isMavenModule="true"" from file.

save and reBuild project.

if you have a pom file in your project, right click the file, click "add as maven project"

This got it back for me. None of the other solutions worked. I had no warnings for unmanged poms, toggling toolbars did not help and the maven option just where it should be anywhere!

Finally found the solution, right-click on the pom.xml file (parent pom.xml if it is a multi-module project) and hit "add as a maven project".

Looks like my maven integration plugin got disabled.

Go to IntelliJ Idea --> Preferences and enable Maven integration plugin.

Looks like Intellij Idea disables dependent plugin also, when one of the plugins are disabled.

Make sure that the home directory of the project is correct. I was creating Intellij project one level above the actual maven project folder and that's why the maven tool window wasn't showing.

Right-click on your project > Add Framework Support > Maven

Try with File-->Project structure --> Modules-> Remove Parent/existing modules and add parent/all modules again

Simple solution to see maven on intelliJ is go to your right click on your pom.xml and then click on Add as Maven project.

None above helped. In my case I had to ad Java SDK. It keeps disappearing for some reason. Right click on project folder -> Open Module settings -> Project in this window define SDK under SDK:

Maven toolbar appeared after doing that.

No Need to do any settings i have attached the image of intelij in that marked area click on that multi window suport then you will be able to access the panels for all
