Cannot find builtin plugin JavaScriptLanguage

I also have this problem when I use new version IU-212.3116-EAP-CANDIDATE-SNAPSHOT.

Hi Rxliuli

I already have an optional dependency on javascript in my plugin.xml.

In my gradle,properties file I have:

intellij {
    version ideVersion
    type 'IU'

    if (isMoreRecent(intellij.version, '2020.2.4')) {
        plugins 'JavaScriptLanguage', 'CSS', 'java', 'completionMlRanking'
    } else if (isMoreRecent(intellij.version, '2019.2')) {
        plugins 'JavaScriptLanguage', 'CSS', 'java', 'stats-collector'
    } else {
        plugins 'JavaScriptLanguage', 'CSS'
    }
}

I tried changing 'JavaScriptLanguage' into 'JavaScript' but then it failed on account of not finding a JavaScript plugin.

This works fine when building with 2021.1 and also worked fine with latest EAP until recently (not sure exactly when this stopped working).

Maybe you can take a look here: https://github.com/JetBrains/gradle-intellij-plugin/issues/674

That sounds related but I'm not sure what to make of it.

People in the JB dev slack channel seem to suggest to just not build with EAP for now:

https://jetbrains-platform.slack.com/archives/C5U8BM1MK/p1622372725206500

why the temporarily remove this javascript? when they will fix it before publish official 2021.2?

It is not removed, it cannot be resolved in current 2021.2 EAP builds by our tooling due to internal/packaging changes.

Is it means the JavaScriptLanguage plugin will be available in 2021.2 GA release?

Simon Jiang Yes, it is a temporary problem we'll solve ASAP.

Hi, 

I wanted to ask if the problem is fixed by now. Because i get the same error message regarding JavaScriptLangauge plugin and i wanted to check if this error is new or the already known one. 

Daniel Alexander Haak it should be fixed as indicated https://github.com/JetBrains/gradle-intellij-plugin/issues/674#issuecomment-879839331, otherwise please post link to your plugin sources

My build.gradle has following configuration: 

intellij {
    version '2021.2.2'//
    type 'IU'
    plugins = ['JavaScriptLanguage', 'com.intellij.java', 'com.jetbrains.php:212.5284.44'] //212.5284.44211.7628.21
}

and as soon as i try to build i get the following error:
Cannot find builtin plugin JavaScriptLanguage for IDE: path/ideaIU-2021.2.2

The information is not complete. What version of gradle-intellij plugin are you using?

i am using Gradle plugin 211.7628.21

I mean the gradle-intellij-plugin defined in your build file.

plugins {
    id 'java'
    id 'org.jetbrains.intellij' version '0.7.3'
}

group ''
version '1.01'

repositories {
    mavenCentral()
}

dependencies {
    testImplementation 'org.junit.jupiter:junit-jupiter-api:5.6.0'
    testRuntimeOnly 'org.junit.jupiter:junit-jupiter-engine'
    implementation group: 'com.googlecode.json-simple', name: 'json-simple', version: '1.1.1'
}

// Ultimate kompatibel
intellij {
    version '2021.2.2'//
    type 'IU'
    plugins = ['JavaScriptLanguage', 'com.intellij.java', 'com.jetbrains.php:212.5284.44'] //212.5284.44211.7628.21
}

This is my entire build.gradle file 

As indicated in the link I gave previously, this is fixed in 1.1.x version, but you're still using very outdated 0.7.3

Hi Yann Cebron : 

[update] : issue solved when I switch type(IC) -> type(IU) ， cause the IC do not have the buildin-plugin JavaScript

--------------------------------------------------------------------------------------

My IDEA version is IntelliJ IDEA 2022.1.3 (Ultimate Edition)，  I also meet this issue ：

Cannot find builtin plugin 'JavaScript' for IDE: ~/.gradle/caches/modules-2/files-2.1/com.jetbrains.intellij.idea/ideaIC/2021.2/b0727ceddea2b62b16825db9308e14a470198e7f/ideaIC-2021.2

the step how to recurrence the issue:

step 1:

Use Idea's [new project], and new a plugin project

step 2:

<depends>JavaScript</depends> in plugin.xml

<!-- Plugin Configuration File. Read more: https://plugins.jetbrains.com/docs/intellij/plugin-configuration-file.html -->
<idea-plugin>
    <!-- Unique identifier of the plugin. It should be FQN. It cannot be changed between the plugin versions. -->
    <id>com.example.demo</id>

    <!-- Public plugin name should be written in Title Case.
         Guidelines: https://plugins.jetbrains.com/docs/marketplace/plugin-overview-page.html#plugin-name -->
    <name>Demo</name>

    <!-- A displayed Vendor name or Organization ID displayed on the Plugins Page. -->
    <vendor email="support@yourcompany.com" url="https://www.yourcompany.com">YourCompany</vendor>

    <!-- Description of the plugin displayed on the Plugin Page and IDE Plugin Manager.
         Simple HTML elements (text formatting, paragraphs, and lists) can be added inside of <![CDATA[ ]]> tag.
         Guidelines: https://plugins.jetbrains.com/docs/marketplace/plugin-overview-page.html#plugin-description -->
    <description><![CDATA[
    Enter short description for your plugin here.<br>
    <em>most HTML tags may be used</em>
  ]]></description>

    <!-- Product and plugin compatibility requirements.
         Read more: https://plugins.jetbrains.com/docs/intellij/plugin-compatibility.html -->
    <depends>com.intellij.modules.platform</depends>
    <depends>JavaScript</depends>

    <!-- Extension points defined by the plugin.
         Read more: https://plugins.jetbrains.com/docs/intellij/plugin-extension-points.html -->
    <extensions defaultExtensionNs="com.intellij">

    </extensions>
</idea-plugin>

step 3：

plugins.set(listOf("JavaScript")) in build.gradle.ktx

plugins {
    id("java")
    id("org.jetbrains.intellij") version "1.5.2"
}

group = "com.example"
version = "1.0-SNAPSHOT"

repositories {
    mavenCentral()
}

// Configure Gradle IntelliJ Plugin - read more: https://github.com/JetBrains/gradle-intellij-plugin
intellij {
    version.set("2021.2")
    type.set("IC") // Target IDE Platform

    plugins.set(listOf("JavaScript"))
}

tasks {
    // Set the JVM compatibility versions
    withType<JavaCompile> {
        sourceCompatibility = "11"
        targetCompatibility = "11"
    }

    patchPluginXml {
        sinceBuild.set("212")
        untilBuild.set("222.*")
    }

    signPlugin {
        certificateChain.set(System.getenv("CERTIFICATE_CHAIN"))
        privateKey.set(System.getenv("PRIVATE_KEY"))
        password.set(System.getenv("PRIVATE_KEY_PASSWORD"))
    }

    publishPlugin {
        token.set(System.getenv("PUBLISH_TOKEN"))
    }
}

and this issue happen.....

Cannot find builtin plugin 'JavaScript' for IDE: ~/.gradle/caches/modules-2/files-2.1/com.jetbrains.intellij.idea/ideaIC/2021.2/b0727ceddea2b62b16825db9308e14a470198e7f/ideaIC-2021.2

Any Solution？ I just want to develop a JavaScript plugin

Edit: the solution for me was to use `JavaScript` instead of `JavaScriptLanguange`, I think.

Hi, I'm getting this issue also with newer versions of gradle-intellij-plugin, using IntelliJ IDEA Ultimate. What am I doing wrong here? Here is the code:
https://github.com/t4lz/mirrord/blob/8a299fad70658ec111ef1e95ad15b14ff6e08ec7/intellij-ext/modules/products/webstorm/build.gradle.kts#L23

This is the error:

Could not determine the dependencies of task ':mirrord-products-webstorm:compileKotlin'.
> Could not resolve all dependencies for configuration ':mirrord-products-webstorm:compileClasspath'.
   > Cannot find builtin plugin 'JavaScriptLanguage' for IDE: /Users/username/.gradle/caches/modules-2/files-2.1/com.jetbrains.intellij.idea/ideaIU/2022.3/56e5440ce30b03c913ff231a46cb1ba6ac4df63/ideaIU-2022.3

Please follow the guide and use plugin ID determined as per https://plugins.jetbrains.com/docs/intellij/plugin-dependencies.html

Thanks you for the advice and the link. The documentation here https://plugins.jetbrains.com/docs/intellij/webstorm.html#configuring-plugin-projects-targeting-webstorm says `JavaScriptLanguage`, is it outdated?

t4lz Thanks a lot for catching this, fixed.
