-mvn exec:java         # run Main.main()

+- `exec:java` requires `-Dexec.mainClass` (the pom does not configure a default `mainClass`).
+- In this environment `mvn` may not be on PATH. Use the IntelliJ-bundled Maven:
+  `C:\Program Files\JetBrains\IntelliJ IDEA Community Edition 2023.3.8\plugins\maven\lib\maven3\bin`
+- PowerShell splits unquoted `-Dexec.mainClass=...`; quote the argument: `'-Dexec.mainClass=space.anyi.Cf01_CreateStage'`.
+- Console shows GBK encoding by default, so Chinese output may look garbled in terminal even though the program is correct.
