IntelliJカスタム言語プラグイン - 言語IDは既に登録されているエラーです

Question

カスタムJavascriptのようなカスタム言語プラグインを構築しています。このカスタム言語は、Ecmascript 6/Javascriptに基づいています。 Javascriptの上に特別なカスタムタグとキーワードを追加したいと思います。最も重要なのは、コードシンタックスのハイライトをJavascriptと同じように見せたいと思っています。私はJava言語で構文の強調表示をテストしています。私はこのコンストラクタとハイライトが私のプラグインをデバッグした後に働いた追加私のMyScriptLanguage.javaファイル内

：

protected MyScriptLanguage() { super(JavaLanguage.INSTANCE, "MyScript", "text/ms", "application/ms"); }

は、その後、私はこのようにJavascriptの言語に切り替える：
protected MyScriptLanguage() { super(JavascriptLanguage.INSTANCE, "MyScript", "text/ms", "application/ms"); }

をへ切り替えた後Javascriptデバッグがいくつかの言語の競合エラーで動作を停止しました

2 MyScriptFileTypeFactory.java

package com.ndoubismarck.mytest.lang.myscript; 

import com.intellij.openapi.fileTypes.FileTypeConsumer; 
import com.intellij.openapi.fileTypes.FileTypeFactory; 
import org.jetbrains.annotations.NotNull; 

public class MyScriptFileTypeFactory extends FileTypeFactory { 
    @Override 
    public void createFileTypes(@NotNull FileTypeConsumer fileTypeConsumer) { 
     fileTypeConsumer.consume(MyScriptFileType.INSTANCE, "ms"); 
    } 
} 

3. MyScriptFileType.java

package com.ndoubismarck.mytest.lang.myscript; 

import com.intellij.lang.Language; 
import com.intellij.lang.javascript.JavascriptLanguage; 

public class MyScriptLanguage extends Language { 
public static final MyScriptLanguage INSTANCE = new MyScriptLanguage(); 

protected MyScriptLanguage() { 
    //super(JavaLanguage.INSTANCE, "MyScript", "text/ms", "application/ms"); 
    super(JavascriptLanguage.INSTANCE, "MyScript", "text/ms", "application/ms"); 
} 

@Override 
public String getDisplayName() { 
    return "MyScript language"; 
} 
} 

誰かが私を助けることができます。私はJavascriptのハイライト機能とオートコンプリート機能を独自のカスタム機能の上に拡張する必要があります。

Answer 1

これは、plugin.xmlのJavaScriptプラグインに依存していないために発生している可能性があります。
