What would cause a mod to work in eclipse but after recompiling it crashes

The current version I'm working with is minecraft 1.5.2 and MinecraftForge v7.8.0.725, now yeah i know taht's not the latest version of forge but don't think that's the problem in this case.

 

Now the mod works fine, until you open up the gui for the crafting tables we have in simcraft, no they are based on the minecraft double chest code, but it's used for a crafting table, this worked like a charm from minecraft version 1.2.5 up until now.

 

What's happening now is in eclipse it works and theirs no error so all is good to go, I recompile the mod reob it and setup a 1.5.2 instance of minecraft with same version of forge used in eclipse, but it keeps crashin on the opening of the gui after it's recompiled.

 

So the question is does anybody have any idea where to look for the problem, I mean it's virtually working in eclipse, but not after being recompiled it doesn't make sense and being a semi noob I don't really know where to look or how to fix something that's already working inside eclipse any suggestion would be appreciated.

Think that's about it, bear in mind this works in eclipse it also worked on version 1.4.7 only place this now crashes is after a recompile and running minecraft outside of eclipse.

Check if you have the same Forge and Minecraft version inside and outside of eclipse.

 

Yeah already checked that and they are the same on both, only difference would be that one comes from the src that forge creates and in game it's the universal jar that's drag into the minecraft jar

 

Also checked the latest 1.5.2 forge build in game and same results.

error is being caused by this  bit, but you should all ready know that.

    public ItemStack getStackInSlot(int var1)
    {
        return var1 >= this.getSizeInventory() ? null : this.parent.getStackInSlot(var1);
    }

 

try splitting it up like so, and give us the new error report

    public ItemStack getStackInSlot(int var1)
    {
        ItemStack stack = null;
        if(var1 < this.getSizeInventory())
            stack = this.parent.getStackInSlot(var1); // I think error will be thrown here.

        return stack;
    }

 

given that it is a java.lang.AbstractMethodError, It is probably that there is an unimplemented method in the class . I'm not definite, but you could try removing any of the unnecessary implementations in the class

public class TileEntityIronWorkBench extends TileEntityCommonWorkbench implements IInventory, IBenchHammer, NetworkTileEntityEventListener, NetworkClientTileEntityEventListener

i.e. if they are implemented by the super class this could be causing you issues by re-implementing them in the sub class, but again not definite just trying to help. (try removing IInventory for example, as I guess that this is implemented by TileEntityCommonWorkbench, the implementation will carry down to the sub classes so that they can also be called as IInventory without having to re state it)

I haven't implemented anything in sub classes that has been implemented in parent class

 

I wish my java was better to tell you the truth, but been battling with updating to 1.5.2 for 2 weeks now on a mod thats almost twice the size of minecraft, and this is the last problem i have which i just don't understand why it can work in eclipse but not after recompiling and in game.

 

What i do see is that getSizeInventory is 9 in the sub class indicating the actual crafting grid to use but the actual block has 27 slots indicated in TileEntity, so might be that will play around but any input is more than welcome cause that just helps one think in different directions.

I can't find where you're creating the getStackInSlot(int var1) method in TileEntityIronWorkBench. My previous response was based on the assumption that this was declared in the super class, but as you're saying that this is not the case (as getStackInSlot(int var1) is an IInventory method) then i don't even know how this is managing to even run in eclipse.

 

a java.lang.AbstractMethodError gets thrown by java when you attempt to call a method which has no method body. i.e. in an interface you create only the method names and parameters, there are no bracers following them. If you do not fill the method in the implementation then this method will be impossible to call giving you the mentioned error http://docs.oracle.com/javase/6/docs/api/java/lang/AbstractMethodError.html

Yeah that gets called in TileEntityCommonWorkbench

 

    public ItemStack getStackInSlot(int var1)

    {

        return this.inventory[var1];

    }

 

i think the biggest part that confuses me is why it's working in eclispe worked in 1.4.7 without hiccups but all of a sudden in 1.5.2 and only after recompiling it fails to load using the same forge version etc, that part really screws with me, and fixing anything where I have to recompile and reob to test is beyond time consuming

 

Edit: InventorySubCraft is basicly a clone of class file InventoryCrafting and extends to it and InventoryCrafting did not change at all from 1.4.7 to 1.5.2 except for one extra method added to 1.5.2, so I'm not even sure that it's the cause of the crash.

::) so does TileEntityCommonWorkbench implement IInventory or not. You've confused me now.

 

try adding

    @Override
    public ItemStack getStackInSlot(int var1)
    {
        return super.getStackInSlot(var1);
    }

to TileEntityIronWorkBench

    • It's using the java 19 version, hence the error. You can do the same exact thing for Java 17 if you want. You could also just put in the absolute path instead of copying it to the server folder. Same way you add any environment variable. It's not specific to only java.
    • I am using a modified MeleeAttackGoal to make an entity pick a random button, go to it and press it. But after a while it just stops and stares at the current button target. I found out that it's just staring at it because it's too far away to press it.  And its's not moving because the current path in the mob navigation is "done". If I move it further away it recalculates a non weird path and fixes itself. If I push it towards the button so it can press it, it sets the target to null, so it once again calculates a new path and fixes itself. What is causing the path to be "done"? And how can I fix this? This is the tick method in the custom goal class: public void tick() { if (mob.buttonTarget != null) { float x = mob.buttonTarget.getX(); float y = mob.buttonTarget.getY(); float z = mob.buttonTarget.getZ(); float hx = x + 0.5f; float hy = y + 0.5f; float hz = z + 0.5f; mob.getLookControl().setLookAt(hx, hy, hz, 30.0F, 30.0F); double distSqr = mob.distanceToSqr(hx, hy, hz); ticksUntilNextPathRecalculation = Math.max(ticksUntilNextPathRecalculation - 1, 0); if ((followingTargetEvenIfNotSeen || hasLineOfSight(mob, mob.buttonTarget)) && ticksUntilNextPathRecalculation <= 0 && ((pathedTargetX == 0.0D && pathedTargetY == 0.0D && pathedTargetZ == 0.0D) || mob.buttonTarget.distSqr(new Vec3i(pathedTargetX, pathedTargetY, pathedTargetZ)) >= 1.0D || mob.getRandom().nextFloat() < 0.05F)) { pathedTargetX = hx; pathedTargetY = hy; pathedTargetZ = hz; ticksUntilNextPathRecalculation = 4 + mob.getRandom().nextInt(7); if (distSqr > 1024.0D) ticksUntilNextPathRecalculation += 10; else if (distSqr > 256.0D) ticksUntilNextPathRecalculation += 5; Path newPath = mob.getNavigation().createPath(mob.buttonTarget, 0); if (newPath != null && !newPath.canReach()) { mob.buttonTarget = null; return; } if (!mob.getNavigation().moveTo(newPath, speedModifier)) ticksUntilNextPathRecalculation += 15; ticksUntilNextPathRecalculation = adjustedTickDelay(ticksUntilNextPathRecalculation); } ticksUntilNextAttack = Math.max(getTicksUntilNextAttack() - 1, 0); checkAndPerformAttack(mob.buttonTarget, distSqr); } }  
    • As of Forge version 44.1.5 and above, Minecraft has started crashing whenever I played it with the Create mod. Without any mods, it loads normally, but when I put in a mod, like MrCrayfish's furniture mod for example, it fails to read the mod properly. Basically I press play and it loads. When the launcher closes, it opens back up again with an Exit Code 1 error, stating that the game crashed due to an unexpected error. Here's my latest.log for more information. https://pastebin.com/pUPBjpbr  
    • The files are harmed by system flaws and glitches. Additionally, the installation procedure might cause files to be lost. The game is so terminated, and an exit code 1 error is displayed. Therefore, attempt a game reinstall.
    • Hello there!  I'm hosting a Minecraft Tekxit PI server on Minecraft 1.12.2 on my computer and I have a little issue. Everything was going great until one day my light in my house went down while a friend was inside the server. The server crashed and when I came back 2 chunks swapped but everything seemed normal. Fastforward in time my friend who was inside the server tried to come back in it but everti-me he tries to join he cannot do it and there is a crash in the server logs. If any other friend tries to join they can, but, that friend that was inside the server when that occurred cannot join. I tried rebooting, rebooting my modem, deleting his player data to start over and nothing works. I'm leaving the crash logs here.
