Java Question SLC Compiling Error

[behnam_tr]

I have a Java project that runs without any problems on Eclipse, but it gives an error when compiling with SLC

Starting step: Compiling Java code.
javac 1.8.0_381
C:\Users\Admin\eclipse-workspace\test1\src\mypackage\firstlib.java:6: error: cannot access SimpleTransferApiImpl
import ir.gov.tax.tpis.sdk.transfer.api.SimpleTransferApiImpl;
                                       ^
  bad class file: C:\Users\Admin\eclipse-workspace\test1\libs\content-0.0.34-jar-with-dependencies.jar(ir/gov/tax/tpis/sdk/transfer/api/SimpleTransferApiImpl.class)
    class file has wrong version 55.0, should be 52.0
    Please remove or make sure it appears in the correct subdirectory of the classpath.


Error.

It's telling you that the class was compiled to run on a later version of Java.
55 = Java 11
52 = Java 8

I believe (though I could be wrong) SLC is for Java 8.

Just noticed 11 isnt on there it's 14 now

Download 11 from Openjdk then add the javafx - make the directories layout the same as 14

If SLC is producing the correct XML file compiling with JDK 11 then you are lucky. The Doclet that produces the XML can produce bad XML or throw errors during compile when used with Java versions later than 8 so where possilbe you should use SLC with Java 8.

Yes, the compilation was done correctly with jdk11 and I also tested the library and it works without problems with jdk11
I was surprised because I had seen in some posts that it is only supported up to jdk8
