java - OptaPlanner 7.21.0 无法从 jar 文件执行 - 目录 dataDir 错误

Question

我正在尝试创建可执行 jar，因为我已经完成了我的应用程序并希望将其导出到其他计算机。然而我收到了错误提示。有什么建议吗？

我已经根据 POM 尝试了带有依赖项和阴影的 Jar

异常(exception):

Exception in thread "main" java.lang.IllegalStateException: The directory dataDir (/home/rodney/Desktop/data/nurserostering) does not exist.
 Either the working directory should be set to the directory that contains the data directory (which is not the data directory itself), or the system property org.optaplanner.examples.dataDir should be set properly.
 The data directory is different in a git clone (optaplanner/optaplanner-examples/data) and in a release zip (examples/sources/data).
 In an IDE (IntelliJ, Eclipse, NetBeans), open the "Run configuration" to change "Working directory" (or add the system property in "VM options").
