Я пытаюсь экспортировать пример ProjectJobScheduling от OptaPlanner как исполняемый файл jar, но получаю следующую ошибку:
Exception in thread "main" java.lang.IllegalArgumentException: The solverConfigResource (org/optaplanner/examples/projectjobscheduling/solver/projectJobSchedulingSolverConfig.xml) does not exist as a classpath resource in the classLoader (jdk.internal.loader.ClassLoaders$AppClassLoader@c387f44).

at org.optaplanner.examples.projectjobscheduling.app.ProjectJobSchedulingApp.main(ProjectJobSchedulingApp.java:36)
Я просмотрел все связанные вопросы в StackOverflow, но мне не удалось решить проблема. Это часть кода ProjectJobSchedulingApp:
public static final String SOLVER_CONFIG
= "org/optaplanner/examples/projectjobscheduling/solver/projectJobSchedulingSolverConfig.xml";
public static final String DATA_DIR_NAME = "projectjobscheduling";
public static void main(String[] args) {
prepareSwingEnvironment();
new ProjectJobSchedulingApp().init();
}
public ProjectJobSchedulingApp() {
super("Project job scheduling",
"Official competition name:" +
" multi-mode resource-constrained multi-project scheduling problem (MRCMPSP)\n\n" +
"Schedule all jobs in time and execution mode.\n\n" +
"Minimize project delays.",
SOLVER_CONFIG, DATA_DIR_NAME,
ProjectJobSchedulingPanel.LOGO_PATH);
}
Как можно решить эту проблему? Возможно, я создаю файл JAR неправильным образом?
Редактировать: Джеффри, спасибо за совет, он решил проблему. Теперь возникла новая проблема, аналогичная this one. Предложенное там решение, а также решение, предложенное Юрло c, не работают. Это код моего pom. xml файла:
