链接到我下面的示例：

文档页面:https://www.jetbrains.org/intellij/sdk/docs/tutorials/code_inspections.html
示例项目:https://github.com/jetbrains/intellij-sdk-docs/tree/master/code_samples/comparing_references_inspection

这是检查的提供者。

package com.magicbytes.kotlin.inspections;

import com.intellij.codeInspection.InspectionToolProvider;
import com.magicbytes.kotlin.inspections.ExampleInspection;
import org.jetbrains.annotations.NotNull;

public class ExampleProvider implements InspectionToolProvider {
    @NotNull
    @Override
    public Class[] getInspectionClasses() {
        return new Class[]{ExampleInspection.class};
    }
}

package com.magicbytes.kotlin.inspections;

import org.jetbrains.annotations.Nls;
import org.jetbrains.annotations.NotNull;
import org.jetbrains.kotlin.idea.inspections.AbstractKotlinInspection;

public class ExampleInspection extends AbstractKotlinInspection {
    @Nls
    @NotNull
    @Override
    public String getDisplayName() {
        return "Kotlin Test";
    }
}

plugins {
    id 'java'
    id 'org.jetbrains.intellij' version '0.3.2'
}

group 'com.magicbytes'
version '1.0-SNAPSHOT'

sourceCompatibility = 1.8

repositories {
    mavenCentral()
}

intellij {
    version '2018.1.4'
    plugins 'kotlin'
}

<idea-plugin>
    <id>com.magicbytes.kotlin.inspections</id>
    <name>Plugin display name here</name>
    <description></description>

    <depends>org.jetbrains.kotlin</depends>

    <extensions defaultExtensionNs="com.intellij">
        <!-- Add your extensions here -->
        <inspectionToolProvider implementation="com.magicbytes.kotlin.inspections.ExampleProvider"/>
    </extensions>

    <actions>
    </actions>
</idea-plugin>

我得到的例外..

在导入GitHub repo并在本地构建之后，我发现./build/libs/kotlin.inspections-1.0-snapshot.jar只包含META-INF，但没有类。我怀疑这是因为您的源代码位于./src/main/src之下，而不是像Gradle项目那样位于./src/main/java之下，所以它只是假设您根本没有代码。

将内部src目录重命名为java后，错误变为

class com.magicbytes.kotlin.inspections.ExampleInspection: group display name should be overridden or configured via XML class com.magicbytes.kotlin.inspections.ExampleInspection
java.lang.Throwable: class com.magicbytes.kotlin.inspections.ExampleInspection: group display name should be overridden or configured via XML class com.magicbytes.kotlin.inspections.ExampleInspection

    at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:617)
    at java.lang.Thread.run(Thread.java:745)

这更好，看起来像是一个单独的问题，因为您的代码违反了一些约定。
