NoClassDefFound inside downgraded jar

[lebedynskyi]

I 've used console comand like:

java -jar jvmdowngrader-0.7.1-all.jar -c 52 downgrade -t vineflower-1.10.1.jar vineflower-1.10.1-down.jar

And after build in prod project with dowgraded jar i see next error in first class (Library enter)

java.lang.NoClassDefFoundError: Failed resolution of: Lxyz/wagyourtail/jvmdg/j9/stub/java_base/J_U_Map;
	at org.jetbrains.java.decompiler.main.decompiler.ConsoleDecompiler.<clinit>(ConsoleDecompiler.java:29)
	...

Inside downgraded class I see these imports:

import xyz.wagyourtail.jvmdg.j11.NestHost;
import xyz.wagyourtail.jvmdg.j11.NestMembers;
import xyz.wagyourtail.jvmdg.j9.stub.java_base.J_U_Map;

IDE does not see its implementation. Do you think I should add some additional library jar to the project?

You might be missing https://maven.wagyourtail.xyz/releases/xyz/wagyourtail/jvmdowngrader/jvmdowngrader-java-api/0.7.1/jvmdowngrader-java-api-0.7.1-downgraded-8.jar or similar at runtime

Now it compiles. Thanks.. Didn't noticed this in docs.. Anyway thanks.

Yeah. It's either that or using the shade method in the docs. which is preferable in many cases
