Posted June 13, 20196 yr Hi, I'm back. I need help with this problem that shows up whenever I try to test my mod. WARNING: An illegal reflective access operation has occurred WARNING: Illegal reflective access by GradleStart (file:/C:/Users/*/.gradle/caches/minecraft/net/minecraftforge/forge/1.12.2-14.23.5.2768/start/) to field java.lang.ClassLoader.sys_paths WARNING: Please consider reporting this to the maintainers of GradleStart WARNING: Use --illegal-access=warn to enable warnings of further illegal reflective access operations WARNING: All illegal access operations will be denied in a future release [17:17:55] [main/INFO]: Extra: [] Exception in thread "main" java.lang.ClassCastException: class jdk.internal.loader.ClassLoaders$AppClassLoader cannot be cast to class java.net.URLClassLoader (jdk.internal.loader.ClassLoaders$AppClassLoader and java.net.URLClassLoader are in module java.base of loader 'bootstrap') at net.minecraftforge.gradle.GradleForgeHacks.searchCoremods(GradleForgeHacks.java:85) at net.minecraftforge.gradle.GradleStartCommon.launch(GradleStartCommon.java:86) at GradleStart.main(GradleStart.java:25) What does this mean? How can I fix it? I am using Java 11 for the 1.12.2 mod and I am using Intellij Idea
June 13, 20196 yr Only Java 8 is supported for 1.12.2 About Me Spoiler My Discord - Cadiboo#8887 My Website - Cadiboo.github.io My Mods - Cadiboo.github.io/projects My Tutorials - Cadiboo.github.io/tutorials Versions below 1.14.4 are no longer supported on this forum. Use the latest version to receive support. When asking support remember to include all relevant log files (logs are found in .minecraft/logs/), code if applicable and screenshots if possible. Only download mods from trusted sites like CurseForge (minecraft.curseforge.com). A list of bad sites can be found here, with more information available at stopmodreposts.org Edit your own signature at www.minecraftforge.net/forum/settings/signature/ (Make sure to check its compatibility with the Dark Theme)
