Aarilight Posted December 14, 2017 Posted December 14, 2017 (edited) [edit: solved] My mod is completed and everything works when I test via `gradlew runClient`. I'm trying to make the first build of it. After fixing multiple issues I've come across one that's left me completely stumped. When I open the creative tabs, I crash and get the following error: java.lang.AbstractMethodError: Method yuudaari/souls/common/block/BarsEndersteel.getCreativeTabToDisplayOn()Lnet/minecraft/creativetab/CreativeTabs; is abstract at yuudaari.souls.common.block.BarsEndersteel.getCreativeTabToDisplayOn(BarsEndersteel.java) at yuudaari.souls.common.CreativeTab.func_78018_a(CreativeTab.java:33) at net.minecraft.client.gui.inventory.GuiContainerCreative.func_147050_b(GuiContainerCreative.java:500) at net.minecraft.client.gui.inventory.GuiContainerCreative.func_146286_b(GuiContainerCreative.java:443) at net.minecraft.client.gui.GuiScreen.func_146274_d(GuiScreen.java:543) at net.minecraft.client.gui.inventory.GuiContainerCreative.func_146274_d(GuiContainerCreative.java:590) at net.minecraft.client.gui.GuiScreen.func_146269_k(GuiScreen.java:501) at net.minecraft.client.Minecraft.func_71407_l(Minecraft.java:1757) at net.minecraft.client.Minecraft.func_71411_J(Minecraft.java:1096) at net.minecraft.client.Minecraft.func_99999_d(Minecraft.java:397) at net.minecraft.client.main.Main.main(SourceFile:123) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:483) at net.minecraft.launchwrapper.Launch.launch(Launch.java:135) at net.minecraft.launchwrapper.Launch.main(Launch.java:28) All of my blocks extend the same base classes which provide their own getCreativeTabToDisplayOn function (because I'm lazy and didn't want to have to write that line on every block i make). I originally had it running setCreativeTab(CreativeTab.INSTANCE); and changed it to this in an effort to fix the problem. It didn't work, obviously. @Override public CreativeTabs getCreativeTabToDisplayOn() { return CreativeTab.INSTANCE; } See my creative tab class, which is instantiated statically. What am I doing wrong? [edit: solved] Seems like for some reason abstract works differently from workspace to game, I have no idea why. I use a function marked as abstract because I know that any instances will have the function implemented, but for some reason it's not in the build. No clue.
