Java コンパイル ターゲットを持つ ant ビルド ファイルがあります。同じ Eclipse ディストリビューションが正常に動作し、他の ant ビルド ファイルを正常に実行します。ただし、この特定のワークスペースでは。Ant ターゲットを実行すると、次のエラーで失敗します。
[javac] C:\MyProject\scripts\build.xml:119: warning: 'includeantruntime' was not set, defaulting to build.sysclasspath=last; set to false for repeatable builds
[javac] Compiling 1 source file to C:\MyProject\build
[javac] Compiling 9 source files to C:\MyProject\build
[javac] java.lang.NoClassDefFoundError: com/sun/tools/javac/Main
[javac] Exception in thread "main" Could not find the main class: com.sun.tools.javac.Main. Program will exit.
BUILD FAILED
コマンドプロンプトからビルドファイルを実行しようとしたところ、同じ問題が発生しました。これは明らかな問題を示していますか。日食にはアリのパスが設定されており、日食で正しい場所を指していることを確認しました。
また、tools.jar もプロジェクト パスに含まれていることを確認しました。
システム情報：
System info:
Windows 7 Enterprise edition, 64 bit
JDK 1.6b35
ANT 1.8.3
どんなアドバイスも役に立ちます。
================================================== ==========================
@MickJ の要求に従って、診断オプションを使用してビルド ターゲットを実行するときの出力も追加しています (Eclipse のすべてのビルド実行構成に -diagnostics を追加しました)。
