Intellij idea unresolved symbol in grails + gwt project - gwt

I have a grails project and I use the gwt plugin 0.6.1. GWT version is configured using ivy.
I have a strange unresolved symbol error when I try to use a class in package com.google.web.*. When I use the complete class names inline idea reports that it cannot resolve the web package. If I import the same class no error ocurres.
I already tried to run grails clean and removed the idea system directory as well - nothing works.
Idea usally import the class when I use smart complete but in this case idea insert the complete classname instead of importing the class.
The web package is found in the gwt-users-2.4.0.jar and gwt-servlet-2.4.0.jar. Both jars are in the classpath but this how the grails gwt plugin organizes gwt dependency.
Error when using full inline claasnames:
No error when using same class in import statement:
Does anyone have an idea?

Fixed already http://youtrack.jetbrains.net/issue/IDEA-81056
Fix is included in the next IDEA 11.1 EAP
http://confluence.jetbrains.com/display/IDEADEV/IDEA+11.1+EAP

I also had similar issue with IntelliJ IDEA, I solved problem by invalidating the idea cache. After invalidating the cache it will reindex all your library and other files. check this answer as well. Grails and IntelliJ Cache Issues

error: unresolved reference: mongodb in Kotlin

I am new to Kotlin. I want to perform basic CRUD operations with Mongo DB and I get the following error:
error: unresolved reference: mongodb
for this line of code:
import com.mongodb.BasicDBObject
I have added the following dependency in the build of the module in Android Studio (Intellij IDE).
implementation 'org.mongodb:mongodb-driver-sync:3.11.0'
What am I missing?
EDIT
This is the project hierarchy. I work with DBOps.kts
I think you are using legacy code.
Here is the correct one for that.
dependencies {
compile 'org.mongodb:mongo-java-driver:2.13.3'
}
Reference : https://mongodb.github.io/mongo-java-driver/2.13/getting-started/installation-guide/
EDIT
I have tried myself, and it works, so I guess there is another issue.
After importing library via Gradle, you could check it is imported correctly from Project -> External Libraries(Check below image)
If you cannot see the MongoDB library from there, there is a possibility that IDE has some problems. So I would recommend reset caches(File -> Invalidate Caches / Restart), clean build, and rebuild the project.

Unable to import RestBuilder to Grails 2.4.5 project

We are using Grails 2.4.5 and are trying to use the RestBuilder class to implement some functional tests for our REST API's.
I have included compile "org.grails.plugins:rest-client-builder:2.1.1" in the BuildConfig.groovy file.
I can see that the plugin is downloaded but do not see the RestBuilder class in any src directory. I also do not see any references to other dependencies that might include RestBuilder.
Could this be an issue when the plugin was upgraded/moved for Grails 3.x?
Thanks,
Kathy
Could this be an issue when the plugin was upgraded/moved for Grails

No.
You are expressing a dependency on org.grails.plugins:rest-client-builder:2.1.1 which depends on org.grails:grails-datastore-rest-client:3.1.4.RELEASE and that is where grails.plugins.rest.client.RestBuilder is coming from. You should see the corresponding jar file under your home directory in /.grails/ivy-cache/org.grails/grails-datastore-rest-client/jars/grails-datastore-rest-client-3.1.4.RELEASE.jar.

Play with Activator Issue on IntelliJ Idea 14

I have the following problem on IntelliJ IDEA 14:
I created a Play (Scala) project using the Activator (v1.2.10). Then, I converted it to an IDEA project using activator idea command. When, I opened the project with IDEA 14 (Community Edition) the SBT module is not enabled. Therefore, a new dependency in build.sbt file is not included in the classpath. Moreover, the project is not listed in IDEA's SBT view.
The following warning is shown by IDEA:
"This IDEA project is converted from an SBT project by gen-idea tool, which currently relies on a legacy Scala project model. Please consider using built-in SBT support via the Import project action."
Note that, the Scala and SBT plugins are already installed on IDEA.
I don't encounter with the same issue in IDEA 13.
Have you tried File | Import Project and select build.sbt file?
IDEA imports it as an SBT project, with all the dependencies properly resolved. It works fine for me on IDEA 14 and on 13.
Apparently, this is a bug in some versions of IntelliJ 14, that just got fixed (as of version 14.0.3). Updating IJ then updating the scala plugin seems to make things work.
In this case simply import manually the "build.sbt" from your project, so if the directory is ~/Documents/myPlayApp then choose to import ~/Documents/myPlayApp/build.sbt

`Cannot find symbol` in IntelliJ 14

I have use the IntelliJ Scala plugin before, in 13 and 13.1. I upgraded to 14, and it doesn't work anymore for my SBT project.
For all Scala standard lib stuff, I see errors like "Cannot find symbol scala.Option".
at scala project, compiler error - Cannot resolve symbol List? says I need to have the Scala facet for my module. I looked in facets, and Scala wasn't an option.
I've uninstalled IntelliJ and the Scala plugin and my settings and the projects files multiple times, but still happens.
How do I fix this?
the new scala plugin for intellij 14 removed the facet and replaced it with Scala SDK library, see blog
for sbt project, I guess the best bet is to re-create your project by:
File -> open -> select the build.sbt of your project in popup -> delete existing project and import
I had a similar issue when a Java module calls an Scala object. The issue was from the wrong setup in Source Folders; the Scala source was in src/main/scala/..., but in the Project Structure, the Source Folders were setup as src by default. When I changed it as src/main/scala, the Java module can find the Scala object correctly.
I fixed this by using the nightly builds of the Scala plugin.
The fixes have now been incorporated into the stable versions.
In my case i just had to reload the IDE...

import lift mapper caught an error missing jar file

hi im creating a lift scala application
this is my problem
when i import net.liftweb.mapper._ package the compiler gives me error...
i tried to add lift-mapper_2.9.1-2.4-M4.jar jar file to build path ,but the error exists..!
the compiler shows..
bad symbolic reference. A signature in package.class refers to term db in package net.liftweb which is not available. It may be completely missing from
the current classpath, or the version on the classpath might be incompatible with the version used when compiling package.class.
Try to add the mapper via SBT or maven configuration?
Anyway, Scala-2.9.1 and Lift 2.4-M4 are very-very out of date. Better use something like that for a good start: https://github.com/lift/lift_25_sbt/
It works out of the box, and you'll only have to add 1 line to add the mapper support for it. (After that, all dependencies would be downloaded and added to the project automatically, by SBT.)
