intellij-idea - 如何以编程方式为 Intellij Idea 创建自定义 Kotlin Inspection

Question

我想为 Intellij Idea 创建一个插件，为 Kotlin 语言提供额外的检查。按照官方文档中为 Java 创建检查的示例，我最终得到了以下代码，但该代码不起作用。

这里是这个项目的存储库链接:https://bitbucket.org/magycbytes/kotlin-inspections/src/master/

我遵循的示例链接:

• 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};
    }
}

这是实际的检查子类。为了简短起见，它什么都不做，但应该加载。注意:我将父类(super class)更改为 AbstractKotlinInspection

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";
    }
}

我的 buid.gradle 文件如下所示:

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'
}

我的 plugin.xml 看起来像这样:

<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>

我用 plugin.xml 文件做了所有链接。但是当我运行时，我在测试 IDE 时遇到异常。感谢任何见解。注意:我正在使用 runIde 来调试插件。

我得到的异常..

Answer 1

在我导入您的 GitHub 存储库并在本地构建后，我发现 ./build/libs/kotlin.inspections-1.0-SNAPSHOT.jar 包含 META-INF只有 ，但没有类。我怀疑这是因为您的源代码位于 ./src/main/src 下，而不是 ./src/main/java 下，因为它是 Gradle 项目的典型代码，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，错误更改为

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

这要好得多，看起来像是您的代码违反某些契约(Contract)的单独问题。
