Hi, I was trying to create a simple test but keep getting error:

com.plugin.test.MessageWriterTest > initializationError FAILED
    java.lang.NoSuchMethodError: org.apache.log4j.WriterAppender.<init>(Lorg/apache/log4j/Layout;Ljava/io/Writer;)V

test task in Gradle looks like this:

test {
    repositories {
        jcenter()
        mavenCentral()
        mavenLocal()
        maven { url 'http://dl.bintray.com/jetbrains/intellij-plugin-service' }
        maven { url "https://dl.bintray.com/antlr/maven/" }
    }
    dependencies {
        testRuntime(gradleTestKit())
        testCompileOnly(
                'junit:junit:4.12'
        )
        testImplementation(
                'org.junit.jupiter:junit-jupiter-api:5.1.0'
        )
        testRuntimeOnly(
                'org.junit.jupiter:junit-jupiter-engine:5.1.0',
                'org.junit.vintage:junit-vintage-engine:5.1.0'
        )

        testCompileClasspath "org.jetbrains.kotlin:kotlin-gradle-plugin:1.2.51"
// experiments
        testCompile files("lib/openapi.jar")
        testCompile files("lib/log4j.jar")
        testCompile files("lib/netty-all-4.1.10.Final.jar")
        testRuntime files("lib/idea.jar")
    }
    useJUnitPlatform()
    testLogging.exceptionFormat = TestExceptionFormat.FULL
}

And the test

package com.plugin.test

import com.intellij.testFramework.LightCodeInsightTestCase
import junit.framework.TestCase
import org.junit.Test

class MessageWriterTest : LightCodeInsightTestCase() {

    @Test
    fun testWriteChanges() {
        TestCase.assertTrue(true)
        TestCase.assertTrue(false)
    }
}

Did you consider using the intellij-gradle plugin instead? http://www.jetbrains.org/intellij/sdk/docs/tutorials/build_system.html

Well, I'd love to. I tried to run with such plugin but it doesn't work out at all. On configuration stage, I get a fail:

Cannot find builtin plugin CSS for IDE

The script

buildscript {
    repositories {
        mavenCentral()
        maven { url 'http://dl.bintray.com/jetbrains/intellij-plugin-service' }
    }
    dependencies {
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:${kotlinVersion}"
    }
}

plugins {
    id "org.jetbrains.intellij" version "0.4.1"
    id 'com.palantir.git-version' version "0.11.0"
}

apply plugin: 'idea'
apply plugin: 'org.jetbrains.intellij'
apply plugin: 'java'
apply plugin: 'kotlin'

dependencies {
    compile "org.jetbrains.kotlin:kotlin-runtime:$kotlinVersion"
    compile "org.jetbrains.kotlin:kotlin-stdlib:$kotlinVersion"
}

intellij {
    version ideaVersion
    updateSinceUntilBuild false
    plugins = [
            "com.jetbrains.php:${phpPluginVersion}",
            'CSS'
    ]
    pluginName 'Component'
}

wrapper {
    gradleVersion '5.1'
}

Sorry, not everything is working. I realised that I used wrong version as a dependence

I ran into the same error. In my case the kotlin-dsl plugin caused the error as it adds many libraries to the classpath including gradle-api-<version>.jar

plugins {
    `kotlin-dsl`
    idea
    id("org.jetbrains.intellij") version "0.4.16" // https://github.com/JetBrains/gradle-intellij-plugin
    id ("org.jetbrains.kotlin.jvm") version "1.3.31"    
}

After removing kotlin-dsl the error was gone.
