I cloned a github repo and trying to import it in Intellij.But it gives me error as:
[error] java.lang.ClassNotFoundException: org.jetbrains.sbt.CreateTasks$

Scala plugin version is:2017.2.13
Have you tried to upgrade your IntelliJ and the Scala plug-in?
Compute.scala uses sbt 1.1, which is not supported by your IntelliJ version.

I uninstalled the program and reinstalled it again but the problem is not fixed. Anyone has an solution to fix the problem? Thanks.
If you are talking about this plugin, its last update is from 2013 for IntelliJ 12. You want the original AspectJ plugin from JetBrains.
Can anyone help me please? I need to setup a completely offline IntelliJ project with gradle and kotlin for our constrained school environment (No Kotlin installed, No Gradle installed, No Internet).
I packed all kotlin dependencies into libs/kotlin but it still tells me, that kotlin.jvm.internal.Intrinsics is not found. You can find the repo here:
Could not perform incremental compilation: Could not connect to Kotlin compile daemon
Could not connect to kotlin daemon. Using fallback strategy.

But same was working with previous IntelliJ versions. Any suggestions would be really helpful.
Just take the last Intellij 2020.2 RC build (which fix this bug) on : https://confluence.jetbrains.com/display/IDEADEV/IDEA+2020.2+latest+builds
And be careful to also install last lombok intellij plugin (0.30.1).
This issue is detailed on https://github.com/mplushnikov/lombok-intellij-plugin/issues/649 and is not entirelly the fault of the plugin (that's why intellij RC must be also installed)
Obviously this solution should be preferred while waiting for a final Intellij 2020.2.1 version.
More detailled information on https://youtrack.jetbrains.com/issue/IDEA-248146 (minimum build version for fix is IntelliJ IDEA 2020.2.1 RC Build #IC-202.6948.36, built on August 18, 2020)

This is caused by mixing different versions of Log4J on the test runtime classpath. Spring Boot pulls in 2.10.0, your build.gradle declares 2.6.2.
If you remove the version from your dependency definition, Spring Boot will define the version and it will work.
So, please replace these two lines
testRuntime("org.apache.logging.log4j:log4j-core:${log4jVersion}")
testRuntime("org.apache.logging.log4j:log4j-jul:${log4jVersion}")
with these:
testRuntime("org.apache.logging.log4j:log4j-core")
testRuntime("org.apache.logging.log4j:log4j-jul")
Alternatively, you can delete the logManager property from the junitPlatform extension and remove both dependencies.

This is a known bug in sbteclipse: https://github.com/typesafehub/sbteclipse/issues/128
You can try commenting out the "doc" project in the Project.scala definition and see if that helps. Otherwise, I think this is a bug in sbteclipse that has to get resolved first.
