我需要構建包含OpenCV的項目。這會很好，但由於某些原因，庫不會進入庫java.library.path。當我嘗試使用庫運行的代碼我得到這個錯誤：使用Maven使用OpenCV構建Java項目
* java.lang.UnsatisfiedLinkError中：在任何的java.library.path * jniopencv_highgui

你運行什麼命令？ IMO java.library.path選項不會自動設置。它應該指向一個包含OpenCV本地模塊的目錄。 – Tome
@Tome，mvn包。所有* .so文件被認爲是在目錄/ com/googlecode/javacv/cpp/linux-x86_64 /和/ com/googlecode/javacv/cpp/linux-x86/ – ftp27
的結果* .jar文件中據我所知，so文件在打包到JAR文件時沒有被使用，它們必須可以直接從文件系統訪問，所以通常最終會得到類似於/ lib /的結構，用於您的jar和/ bin /（或其他） so/dll文件。/bin /必須是運行程序時必須提供的java.library.path VM選項的值。 – Tome
