/ 30 мая 2019

Я получил проект GettingStarted от ProM-GettingStarted . Я импортировал его в Eclipse после установки плагина Ivy. Но когда я пытаюсь скомпилировать его, консоль показывает «BUILD FAILED».

  • Я пытался изменить JDK с 1,7 до 1,8 и обратно до 1,7 снова.

  • Когда я ввожу 'java -version' и 'javac -version' в 'cmd window', я вижу правильную информацию.

  • Я скопировал инструменты. jar из jdk / lib в jre / lib.

  • Я искал решения, но ничего не помогло.
