I'm trying to use the barbecue barcode printing library. I have successfully added the library to IntelliJ through project structure add library. Then I imported the packages and wrote the methods, which gave me no error. The packages were available in the class.
But when I compile it gives me the error:
error: package net.sourceforge.barbecue does not exist
How can this be?
I'm coding in ubuntu, is there any other place to which I have to add the library?
Just reimport didn't work. Following worked for me.
File -> Invalidate Caches /Restart
Then
Build -> Rebuild Project
That will reimport maven project.
Note : You need to invalidate the cache AND ALSO rebuild the project.
I tried to "Maven > Reimport" but the only thing that actually fixed it was to close the project, delete the .idea directory, and reopen the project.
pom.xml files in the project are added or recognized as Maven Projects by IntelliJ. The file icon should be a small m. If not, right click the pom.xml file, and choose Add as a Maven Project –
Meijer None of the 13 existing answers worked for me. However, I could resolve the issue by first removing all modules:
File > Project Structure...,Modules tab,then removing all remaining Maven modules from Maven tool window:
Remove projects,and then adding them again in Project tool window:
pom.xml,Add as Maven project,now unignoring any ignored modules from Maven tool window:
Unignore,and finally rebuilding using Build > Rebuild project. This assumes that a mvn clean install already happened.
Right click your project / Maven (at bottom) / Reimport
Edit, much later: I also saw this happen much more frequently when I had the Clover plugin installed. Drop that plugin like a bad habit!
In my case the only thing that worked is:
mvn idea:idea
The good thing is that you don't have to delete .idea folder or .iml files and loose all configuration. Everything will be preserved.
(Possibly something like gradle idea works for gradle too).
menu -> build -> Rebuild Project
has worked for me
(Invalidating caches without this step doesn't help)
I did re-import all maven projects. This worked for me.
If you added a library to the project structure (rather than via maven, that would be different), be sure it is included as a dependency for the relevant module.
Project Structure -> Modules -> Dependencies
It's a very annoying problem which happens quite often. Especially after switching to a different git branch. It wasted me way too much time to troubleshoot this kind problem. I have tried all the methods above. But I can't find a reliable way. Here I just summarize those steps which could help in my situation. Jetbrains, please fix this issue to save your customer's precious time.
In my case the problem was that there was a different repository directory configuration in IntelliJ and in settings.xml file.
Check both repository directories are the same:
IntelliJ (File > Settings > Build,Execution,Deployment > Build Tools > Maven )
settings.xml
(usually in C:\Users\myuser\.m2 or /home/myuser/.m2)
<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0
http://maven.apache.org/xsd/settings-1.0.0.xsd">
...
<localRepository>C:\Users\myuser\.m2\repository</localRepository>
...
</settings>
After fixing directories run:
Tried all the above approaches, didn't work.
Finally running maven clean install solved it!
mvn clean install actually worked... –
Argyrol Quit IntelliJ, remove every .idea directory:
rm -Rf **/.idea/
and restart.
Invalidate Caches/ Restart and then Build -> Rebuild Project helped for me
I tried all appreciated answers and none of them solve my problem!
According to Intellij community, there is a bug with Maven builds in 2020.1 and 2020.1.1 versions: https://youtrack.jetbrains.com/issue/IDEA-237320?_ga=2.235486722.203129946.1591253608-322129264.1584010541
Please try to run on 2019.3.4 version (Its worked for me from the first time)
You can download from here
path.macros.xml file has helped me: youtrack.jetbrains.com/issue/… 2020.1 works now. –
Hepcat Similar to cvdr. Too high a Java version can be the problem.
A collegaue just have this problem with multiple java sources in our test project. She had just updated to a later Intellij and when we investigated none of the rebuild options worked but Intellij seemed to have 'bumped' the project Java settings to Java 11 (I guess it takes highest installed version on upgrade install?) Setting it back to Java8 and the project compiles successfully.
Go File>Project Structure > Project Settings > Project and select the right ones in the drop downs.
I got this error after I changed pom, and I fixed it by execute:
mvn idea:module
it works for me
Here is a solution worked for me:
Disable the "Use --release option for cross-compilation like the following in intellij idea:
got Settings -> Build,Execution,Deployment -> Compiler -> Java Compiler and disable:
Use '--release' option for cross compilation(java 9 and later)
As someone who only occasionally needs to do Java work, this was very annoying. Inevitably, packages would have been added since the last time I ran our server inside IntelliJ and it would fail to build. I found what seems to be an easier solution: just don't build within IntelliJ. Build from the command line via Maven, then make sure that the run configuration does not list Build as a "Before launch" task.
I tried
in different combinations.
But going from Intellij 2020 version to 2019 solved my issue.
I had this problem in IntelliJ 2020.3 and tried the invalidate cache option and rebuild, but the problem persisted. The only thing that fixed it was to rename the package and rename it back to what it was originally.
I had the same problem and it was fixed for me by changing the "Maven home directory" in Settings from "Bundled" to my locally installed maven. Perhaps this triggered some kind of refresh somewhere since I had not changed this setting for months without any issue.
What happens here is the particular package is not available in the cache. Resetting will help solve the problem.
Goto terminal and build the project again
./gradlew build
This should download all the missing packages again
If you are trying the suggested ways and still no chance, be sure about your order:
If you did not invalidate and restart cache just after deleting your .idea/, Intellij keeps generating it and that was keeping error in my case.
I had the same issue with my unit tests. I created tests on my master branch and early everything worked well, no matter what branch I was using. But when I switched again to master branch, tests did not work anymore. What helped me was to:
close intellij -> delete .idea file from directory -> open project again by pom.xml (idk if it matters what way you open the project, but first time when I tried to open it normally by intellij, it still dit not work) -> reload all maven projects from right menu -> rebuild project and that's it, everything works now
I had the same problem. I fixed it by applying the android-apt plugin https://bitbucket.org/hvisser/android-apt
Maven reimport, rebuild and invalidate caches did not work. I solved it by opening a terminal and executing maven clean install in the root folder project. (IntelliJ was opened and I was able to see the IDE updating and triggering reindexation while maven was doing his job)
The above solutions didn't work for me. I had to add the dependency explicitly in the pom.xml.
Just add your jar under resources/library and then add it as a dependency in your pom.xml like:
<dependency>
<groupId>your-jar-group-id</groupId>
<artifactId>artifact-id</artifactId>
<version>1.0</version>
<scope>system</scope>
<systemPath>${basedir}/src/main/resources/library/name-of-jar.jar</systemPath>
</dependency>
Try this out if none of the above work.
I solved this problem by updating my local JDK 17 to oracle JDK 17.0.7.
I can't remember which distribution I was using.
If you do not want to destroy .idea, you can try :
In case you're facing very weird "unable to resolve java, sun packages problem", try the following:
I tried compile a java 8 project with JDK 12 and has the same issue. None of previous answer solved my problem.
I changed o Shortel Command Line to "JAR Manifest" and worked like a charm.
Follow the steps below:
I created two new classes under a new package and used it in rest of the code, Intellij was able to resolve these no red highlights were shown in the intellij editor. While building it was showing package doesn't exist error. I tried everything from gradle clean build, rebuild project, clear .idea and .gradle and reimporting the project, clearing the gradle local cache but nothing was working. Finally I refactored the name of the new package and this time intellij was able to recognize the new classes and it started working.
Invalidate caches worked for me but it's too long to recover the caches so I don't have the patience to wait for it. I found another way to solve it in my case. "Repair IDE" step 3 (delete Package search project caches) worked for me perfectly
package com.example;
import com.sun.jna.Library;
import com.sun.jna.Native;
public class C {
public interface Kernel32 extends Library {
public void OutputDebugStringA(String Text);
public void DebugBreak();
public void Sleep(int a);
}
public static int incint(int in1)
{
testpkg.xxxBird.Say("xxxee"); //only use this statement to call external lib
//I don't use "import" statement.
return in1*2;
}
}
I am using intellij idea.
You need to add testpkg path in project dependency.
I faced the same situation in ver 2022.1.4. I tried all solutions from the first answer, nothing worked except the delete the ".idea" folder. Even through many friends mentioned this solution, I couldn't find this folder, I was looking around user profile and AppData folders. This folder was in fact created under the project folder itself.
I closed the project, and re-opened after deleting this folder.. everything back to normal. It felt like the "Intel" was lost and the IDE was only "lij" for sometime.. lol
I tried all answers, but eventually what helped me was changing the Maven from bundled to my own Maven distribution.
I think vice versa (changing from own to bundled) will help as well.
For me, to simply quit IntelliJ and reopen it was enough to get beyond this error.
I don't know if this may help but I've tried all of the solutions mentioned here and more. NOTHING SEEMS TO WORK.
I even look every related issues raised on github issues in Jetbrains and Nothing.
And I was about to loose my mind and started pulling out my hairs and something cames out to my mind.
What I did was use a <dependencyManagement> </dependencyManagement> on my project and specify all the versions and everything then mvn clean install and then on another project I added the dependency as we normally do then IntelliJ, Vscode, started to recogize my imports and classes.
I hope it will also work for you.
