I'm working on a maven project in Spring tool suite(STS), issue is unable to navigate to other classes and methods (using ctrl+ mouse click), and its showing many error messages near import statements and other places in the class.
When clicked on the red cross mark which states error and select FIX project setup below is the message displayed on popup window.
The following proposals have been found to fix the unresolvable reference to 'Bootstrap'
Add archive 'lpa-core-1.2.5.jar - c:\Users\tom.m2\repository\com\lpa\lpa-core\1.2.5' to buildpath of 'lpa-realtime-service'
Please suggest how to include .m2 file automatically while build process to avoid the error messages and to navigate to other classes and methods using ctrl and mouse click.
It sounds like your project is not properly set up so that the IDE doesn't really configure its classpath correctly. Normally this would all happen automatically via m2e (i.e. Eclipse's maven support).
M2e is included in STS by default, so its probably installed, but somehow your project isn't treated as a maven project.
You can try to re-import it using the proper 'import wizard' which should set things up correctly for you.
Steps:
Delete the project from the workspace. Take care not to actually delete the files themselves. (There's a checkbox 'Delete project contents on disk', so don't select that).
clean out all the 'junk' data from your project. Delete all tese files / folders from your project .classpath, .project, .settings, target.
Now that you have a 'clean slate'. Import it using m2e. Menu: File >> Import >> Existing Maven Projects".
This should setup everything correctly.
I say should because it depends to a large degree on what is in the project itself. But this, in principle, is the correct way to import maven project into STS (or Eclipse in general).

Hi,
I am currently facing two issues while remote debugging. Googled around but haven't been able to fix'em.
Despite the source code being available within the project, the
debugger always stops in the maven sources. Question : Is there a
setting/workaround that boils down to "Prefer project modules over maven sources while debugging" ?
Idea showed a popup showing the alternate sources initially. After selecting local module i disabled it. Now i can not re-enable it (for other local modules). The intended behaviour was that it automatically goes to local module source but that not working. Not irritating enough, Preferences -> Build -> Debugger -> "Show alternate source switcher" is not working. It always keeps disabled no matter what i do.
Any inputs are much appreciated.

Update
Solution for #2 is to do it the hard way. Open up
/Users/user-name-here/Library/Preferences/IdeaIC15/options/other.xml
and set 'SHOW_ALTERNATIVE_SOURCE' to true i.e.
<option name="SHOW_ALTERNATIVE_SOURCE" value="true" />
and restart IDEA
Even I had the same problem. I had external jars files attached in the Project_Structure -> Modules -> Dependencies. I did the following trick, it worked for me and it is not the remote debugging. I attached the source code of those jar files in Project_Structure -> Libraries and click the + in the second window pane (I am using Intellij Idea Ultimate 2018.2) then java option in the drop-down list. After selecting java option, a file browser window will open up, choose the source code directory you want to attach during the debugging.
I can see the dependency hierarchy in eclipse, how can I do it in intellij ?
I also like the Maven Helper Plugin.
Allows you to see dependencies as a tree, see conflicts, search in them. It looks a lot like the Eclipse tooling.
Notice the Text and Dependency Analyzer tabs that appear at the bottom of the POM editor panel. Click the analyzer tab to see results as shown in this screenshot.
You can try:
Menu -> View -> Tool Windows -> Maven Projects
And then you can see new view openned.
Open your Dependencies tree, and you can see all the dependency hierarchy.
Offical documentation: View Maven dependencies as a diagram
Open the pom.xml, right click anywhere in the editor and choose "Diagrams > Show Dependencies".
It opens a dependency tree like those I'm attaching.
The main point is that this context menu appears only on opened pom.xml file (at least I couldn't managed to open it from anywhere else), if you just click on the file in the project tree, it won't be present.
Please note: You need to have UML Support and Maven Integration Extension enabled for this.
Use the shortcut Luke! Ctrl + Alt + Shift + U
Or select View -> Tool Windows -> Maven Projects
...here you can either:
A) expand the Dependencies sub-tree,
or
B) select the project ("spring-boot" in my case), a new icon reveals itself
Select Module or Directory and then Analyze from main menu
I love this plugin Maven Helper, but for some reason it was crashing my IntelliJ:
IntelliJ IDEA 2020.2.1 (Community Edition)
Build #IC-202.6948.69, built on August 25, 2020
I tried updating from the marketplace from within IntelliJ, but for some reason it didn't help.
I managed to solve this by installing it from the plugin website Maven Helper by clicking on "Install to IDE".
As mentioned #Ondrej Burkert the Maven Helper Plugin you can select the pom.xml file and if the editor is open there are two tabs at the bottom. First is 'Text' and second is 'Dependency Analyser'. In the tab 'Dependency Analyser' you have a tree of all dependencies like in eclipse.
Menu -> View -> Tool Windows -> Maven Projects is impractical and must be collapsed one by one. I prefer the plujin mentioned by Basil Bourque in this post.
I have a very simple question, but I Googled and somehow I couldn't find it. I was wondering how can I get the
in Intellij 14 or something similar?
I saw it in a tutorial, but couldn't find the panel. In my case when I followed this video exactly, I couldn't see the panel and I couldn't find it anywhere. I have IntelliJ 14.
UPDATE
I just experimented a bit with the Intellij interface but I can't seem to see the right hand side bar. See
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.
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.
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".
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.
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.
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.
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.
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
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!
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.
Right-click on your project > Add Framework Support > Maven
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
Try with File-->Project structure --> Modules-> Remove Parent/existing modules and add parent/all modules again
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.
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
Check if at the bottom line of Intellij, it says "non-managed pom files found."
You can then "Add as a Maven Project"
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.
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.
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
So I accidently added a few plugins, whichs name I have forgotten to the runtime configuration of my application. Since then a ton of not needed contributions to the UI where made:
Help-> "Like 5 new links"
New Entry "Window"
Menu-Icon-Bar: Open Task, Create new visual class.
I'm unable to figure out what the responsible plugins are (There are about 300 plugins selected). If you happen to know which plugins make these contributions please let me know.
You can get the minimum set of plugins needed for your RCP using:
Open the Run Configuration for the RCP.
Go to the Plug-ins tab.
Click Deselect All
Select your plug-ins in the Workspace
Click Add Required Plug-ins
You should end up with just the plug-ins required. Use the -clean option on the next run to make sure the plug-ins cache data is rebuilt.
