我正在尝试将OptaPlanner的ProjectJobScheduling示例导出为可执行jar文件，但出现以下错误：
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.common.app.CommonApp.init(CommonApp.java:110)
at org.optaplanner.examples.projectjobscheduling.app.ProjectJobSchedulingApp.main(ProjectJobSchedulingApp.java:36)
我已经查看了StackOverflow上的所有相关问题，但无法解决问题。这是ProjectJobSchedulingApp代码的一部分：
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);
}
我该如何解决这个问题？也许我以错误的方式创建了jar文件？
编辑：Geoffrey谢谢您的小费，它解决了问题。现在出现了一个新问题，与this相同。其中建议的解决方案以及Yurloc建议的解决方案均无效。这是我的pom.xml文件的代码：
