@linghengqian Nice. Yes for newer libs there is also that DynamicCLassLoader. BTW are you sure about those \\$ escapings? They were important in the shell script, I don't think you need them in your Strings in Groovy. My 2 cents.

- The escape character is automatically added by the IDE when copying and pasting. It seems that only in this way, the build Log of NativeTest is normal.

• @phejl I noticed an issue with my comment earlier while working on apache/shardingsphere#21347, I just updated my comment above. You are correct, I misunderstood something earlier due to Gradle Cache.

• And due to issues on the Junit 5 Platform side, not all mockito-inline 4.11 use cases pass nativeTest properly.
