Drools 5.4.0.Final Javaで実行できません8

Question

Caused by: java.lang.RuntimeException: The Eclipse JDT Core jar is not in the classpath 

私はクラスを構築しようとすると上記のエラーに遭遇しています。私はDrools 5.4.0.Finalを使用していると私は手動で私のビルド・パスにecj-4.5.1.jarを追加したが、それはまだ書かれています：

JDTコアがないクラスパスに。

私は誰もが解決策を提案することができますEclipse Mars、Jdk 1.8、drools 5.4.0.Final

を使用していますか？

EDIT：（のStackTraceを追加しました）

Answer 1

私はECJ-4.5.1.jarを追加した後、問題が修正されました。問題は、ecj jarがプロジェクトと同じクラスパスの下になければならないということでした。 jarのクラスパスが異なる場合、ecj jarをライブラリフォルダの下に追加すると動作しません。
