I have recently upgraded to Intellij 2019.2.1 CE and created a new project with several modules. The new modules are created with only the build.gradle file. The src folder is missing.
On previous version, there was an option under Deployment -> Build Tools -> Gradle -> check the "Create directories for empty content roots automatically". to remedy this.
The new version does not have this option.
How do I get IntelliJ to generate the folders as before?
Alternative will be provided in 2019.3 version: https://youtrack.jetbrains.com/issue/IDEA-216938
I'm using IntelliJ.
I can run Java or Kotlin project without any issue but
I can't build Kotlin-JS project
I have the error Error: Could not find or load main class MainKt
My IntelliJ information

My main file contain just :
fun main(args: Array<String>) {
val message = "Hello JavaScript!"
println(message)
}

I tried the option $KOTLIN_BUILDED$, $MODULE_WORKIN_DIR$, and to put the path manually but it didn't change anything.
When I'm hovering MainKt with my mouse, a tooltip appear "Class 'MainKt' is in the default package" so IntelliJ see the class.
My project settings seem to be ok
Project Structure part 1

I also tried to
Delete the *.iml file
Reinstalle IntelliJ
Re add the main
Invalidate cache and restarted
Thanks you in advance
The "Kotlin" run configuration runs Kotlin/JVM. To run a Kotlin/JS program as a command-line program, you need to make sure you have node.js installed. Then you can either use IntelliJ IDEA Ultimate with the node.js plugin installed (in which case you will see a "run" icon in the gutter that will produce the correct run configuration automatically), or use Gradle to build and run your program from the command line.
Your main file need to be .kt
You need to create it like this: src ->New ->Cotlin File/Class->File.
NOT like this: src ->New ->File.
I am trying to import a Gradle project into IntelliJ, and when I get to the Gradle Home textbox, it is not automatically populated, nor will typing in the path of Gradle Home result in a valid location - I have the GRADLE_USER_HOME environment variable set (to what I think is!) the correct path, and I have been able to successfully import this same project into Eclipse. Any suggestions?
You can write a simple gradle script to print your GRADLE_HOME directory.
task getHomeDir {
doLast {
println gradle.gradleHomeDir
}
}
and name it build.gradle.
Then run it with:
gradle getHomeDir
If you installed with homebrew, use brew info gradle to find the base path (i.e. /usr/local/Cellar/gradle/1.10/), and just append libexec.
The same task in Kotlin in case you use build.gradle.kts:
tasks.register("getHomeDir") {
println("Gradle home dir: ${gradle.gradleHomeDir}")
}
Installed on a Mac via Homebrew, the path
/usr/local/opt/gradle/libexec
is preferable to
/usr/local/Cellar/gradle/X.X/libexec
since the former will survive version upgrades.
If you installed gradle with homebrew, then the path is:
/usr/local/Cellar/gradle/X.X/libexec
Where X.X is the version of gradle (currently 2.1)
If you are using IntelliJ, just do the following.
Close the project
(re)Open the project
you will see "Import gradle project" message on the right bottom. click.
select "Use default gradle wrapper". not "Use local gradle distribution"
That's all.
This is what helped me solve the problem of not having Gradle home set for the IDEA when importing a Gradle project.
THREE OPTIONS -- (A) Default Wrapper (B) "gradle 'wrapper' task configuration" OR (C) "local gradle distribution" defined by jetbrains: https://www.jetbrains.com/help/idea/gradle-settings.html
A. Default Wrapper (recommended)
If you are able, select this recommended option. If it is grayed out, see option C, which should then set your default for all subsequent projects.
B. Gradle 'Wrapper' Task Configuration
If you want IDEA to define your gradle version for you from your build script
Set this option if you define your gradle build versions as a task within your actual gradle build.
Example below from jetbrains: https://www.jetbrains.com/help/idea/gradle-settings.html
(useful if you do not want to share gradle builds between projects)
C. Local Gradle Distribution
1. Run the following command to get gradle location:
brew info gradle (if gradle was installed with homebrew)
2. You are looking for something like this:
/usr/local/Cellar/gradle/4.8.1
3. Next, append 'libexec' to the gradle location you just found:
/usr/local/Cellar/gradle/4.8.1/libexec
This is because "libexec is to be used by other daemons and system utilities executed by other programs" (i.e. IDEA). Please see https://unix.stackexchange.com/questions/312146/what-is-the-purpose-of-usr-libexec
4. Finally, put that new path in the Gradle home input box if IDEA prompts you.
IDEA should now have allowed you to hit OK
C:\Users\<_username>\.gradle\wrapper\dists\gradle-<_version>-all\<_number_random_maybe>\gradle-<_version>
\Android studio\gradle didn't worked for me.
And "Default gradle wrapper" wasn't configured while importing (cloning) the project from bitbucket
If it causes problem to figure out the path, here is my path :
C:\Users\prabs\.gradle\wrapper\dists\gradle-5.4.1-all\3221gyojl5jsh0helicew7rwx\gradle-5.4.1
This is instruction for MAC only.
I had the same problem. I solved it by configuring $GRADLE_HOME in .bash_profile. Here's how you do it:
Open .bash_profile (usually it's located in the user’s home directory).
Add the following lines to update $PATH variable:
export GRADLE_HOME=/usr/local/opt/gradle/libexec
export PATH=$GRADLE_HOME/bin:$PATH
Save it.
Apply your changes by running
source .bash_profile
I wrote my own article with instruction in a case if somebody will encounter the same problem.
On a mac it should ideally be at : /Applications/Android Studio.app/Contents/gradle/gradle-2.14.1
(Replace the version string with the latest)
AFAIK it is GRADLE_HOME not GRADLE_USER_HOME (see gradle installation http://www.gradle.org/installation).
On the other hand I played a bit with Gradle support in Idea 13 Cardea and I think the gradle home is not automatically discover by Idea. If so you can file a issue in youtrack.
Also, if you use gradle 1.6+ you can use the Graldle support for setting the build and wrapper. I think idea automatically discover the wrapper based gradle project.
$ gradle setupBuild --type java-library
$ gradle wrapper
Note: Supported library types: basic, maven, java
Regards
If you're using MacPorts, the path is
/opt/local/share/java/gradle
I had to setup the Project SDK before selecting gradle path. Once that was set correctly, I had to choose "Use default gradle wrapper (recommended) in "Import Project from Gradle" dialog.
Still works if I remove gradle using brew:
$ brew remove gradle
This is where my gradle home is (Arch Linux):
/usr/share/java/gradle/
I had some weird errors where it could not find my class, I had to right click on my src folder (was red) to "Make Directory as" -> Source Folder Root
Click New -> Project from existing sources -> Import gradle project...
Then Idea recognized gradle automatically.
I couldn't get it to accept my Gradle JVM selection until I deleted a broken JDK
Th window below is from File -> Other Settings -> Structure For New Projects...
I had a red 1.8 JDK SDK entry here, once I deleted that Gradle JVM error below disappeared and I could move on to the next step
In case you are using Mac, most probably your gradle home should be /usr/local/gradle-2.0 for example.
In preference of IDEA search for gradle and set gradle home as given above.
It should work
I am trying to use the MSSQL driver for JDBC. I have followed the instructions on how to add an external JAR file to the Eclipse Windows IDE as follow:
- Download the installation from here http://msdn.microsoft.com/en-us/sqlserver/aa937724.aspx (Microsoft JDBC Driver 4.0 for SQL Server)
- Extract the zip to a file location I have extracted it here (c:\MsJDBCforSqlDriver)
- In Eclipse Package Explorer right click your project -> Build Path -> Configure Build Path -> Java Build Path -> Libraries Tab- Add External JAR file and then I browse to
"C:\MsJDBCforSqlDriver\sqljdbc_4.0\enu\sqljdbc4.jar"
- I then view the successful reference as in image below including SQLServerDriver.class
When I try to execute Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver") I get a ClassNotFound Exception as below:
I tried all suggestions I could find on Google including setting the classpath in Windows Environment Variables.
Under the Run -> Run Configurations menu item you should find an entry for a Java application with the same name as the class that contains your main() method.
Have a look at the classpath tab. You should find your project listed under user entries. Expand it and see if the Microsoft JDBC Jar is listed.
The class path you use for compilation need not be the same as you choose for runtime, though Eclipse usually mirrors any changes to your build path to any launch configurations.
Your spelling and case for the package and class names look correct (Java is case-sensitive on names).
And yes, learning Java and Eclipse will take effort - Eclipse is quite different from other IDEs and it takes time to get to know it.
I found the answer here: http://code.google.com/p/android/issues/detail?id=27490
Seems like includes under Referenced Libraries is not available at runtime and I couldn't see how to change this in my version of Eclipse

Reported by fred...#mobileinteraction.se, Mar 22, 2012
Host OS: Windows 7 x64
SDK tools version: 17
Eclipse version: 3.7.2
ADT plug-in version:17.0.0v201203161636-291853
Platform targeted by your project: 2,2
Version of the platform running in the emulator: 2.2
STEPS TO REPRODUCE:
1. Create a project that uses external jars (in my case android-support-v4.jar ).
2. Added the android-support-v4.jar using Properties - Java Build Path - Add External Jar. Have the Activity extends from FragmentActivity.
3. Clean and run project
EXPECTED RESULTS: Application would run launching the FragmentActivity
OBSERVED RESULTS: Application crashes, android-support-v4.jar is placed within "References Libraries" and thus Android can't find it at runtime.
SOLUTION:
Manualy create a folder /libs within your project, copy the android-support-v4.jar to that folder and the ADT will place it under 'Android Dependencies' and it works.
This is the case for all external jars added using Properties - Java Build Path - Add External Jar.
"
Adding the JDBC driver of MS SQL Server to Eclipse:
Download the JDBC driver and uncompress it
Secondary click in the root of the Eclipse project and go to "Properties".
Now go to the section "Java Build Path - Libreries" y then click "Add External JARs".
Search the "sqljdbc.jar" file in the directory where you unpacked the downloaded driver, double click y finish pressing "ok".
I faced the problem and then solved the issue i.e. If You are using the Tomcat as a server for your Web application, the same Exception was coming as the Driver was unavailable to the project, later I put the jar file (sqljdbc4-2.0.jar) into the WEB-INF/lib folder then it was working
When I try to make a simple module in IntelliJ it responds with:
Fatal Error: Unable to find package java.lang in classpath or bootclasspath
Somehow the JDK language jars were removed from the classpath. All I had to do was reapply the JSDK home path.
Goto:
File -> Project Structure -> Platform Settings -> SDKs
Re-apply the JSDK home path.
Doing this added about 15 jars to the classpath. Apparently these are important for compiling.
File -> Project Structure -> Platform Settings -> SDKs, remove existing SDK and add it again.
Works for me in IntelliJ 2017.3.
This error happend to me after i've updated my JDK version to jdk1.8.0_161 -
But the project's sdk was still pointing to the old jdk 1.8.0_131
(Seems that updgrading java causing the previous version to be wiped).
Do this:
In the IntelliJ IDE go to File > Project Structure, from there:
Within Platform Settings > SDKs:
Make sure that the JDK Home path field is pointing to a valid JDK folder (add a new entry if needed e.g. jdk1.8.0_161).
Within Project Settings > Modules:
Make sure that the Module SDK is set to the same entry you picked in the Platform Settings > SDKs
Save & Build again.
This worked for me:
In Preferences Build Tools > Maven > Runner > Environment Variables set JAVA_HOME to your JDK home path.
Usually you want to use the same Java JDK you are using in IntelliJ. You can find that under Project Structure > Platform Settings > SDKs under JDK home path.
e.g. /Library/Java/JavaVirtualMachines/jdk1.8.0_66.jdk/Contents/Home
In Intellij Community 2019.1, this is what I did to solve the issue
Project Structure > Platform Settings > SDKs
Removed all existing SDKs listed ( I had multiple SDK listed there)
Add the required SDK only and Apply
File > Project Structure
JDK home path : PASTE_THE_JDK_LOCATION (Like here in the "Project Structure screen shot"
Build Again
Cheers :)
After following this answer,
I learned that %LOCALAPPDATA%/IDEA/config/options/jdk.table.xml contained incorrect entries. Fixing the JDK table fixed the problem.
