java.util.Map $ Entry尚未解决

Question

I'm writing a mod (attempting) and an error I have never before seen pops up on my package deceleration screaming

"The type java.util.Map$Entry cannot be resolved. It is indirectly referenced from required .class files"

As far as I know requesting help in the direction of minecraft is a no no but I think this qualifies as a java question

package com.DGmoN.mysticPower.items;

import java.util.Set;

import com.DGmoN.mysticPower.lib.Strings;

import net.minecraft.creativetab.CreativeTabs;
import net.minecraft.item.ItemPickaxe;
import net.minecraft.item.ItemTool;

public class MPIPickAxe extends ItemPickaxe {

    protected MPIPickAxe() {
        super(ToolMaterial.EMERALD);
        setUnlocalizedName("MysticPickAxe");
        setTextureName(Strings.MODID + ":" + getUnlocalizedName());
        setCreativeTab(CreativeTabs.tabMisc);
    }

}

Running jdk1.8.0_05 Eclipse Indigo, I haven't used any thing I know of in the direction of the Map thingy.

Answer 1

您指向错误的jdk，请检查jdk路径并清理构建。

Answer 2

This error only occurs when you don't point to correct jdk. Check jdk path and clean build your project.

Answer 3

I have found a different question , the error is similar, and it works, the problem wasnt my jdk but my IDE. Ive changed to Kepler and all my problems are gone

Answer 4

I got the same error when I moved my project from JRE6 to JRE8 directly in eclipse. To resolve this error, I have installed JRE7 and first compiled the code with JRE7 and later with JRE8. My issue got resolved, give a try if this helps you.

Answer 5

项目>属性>库>选择jre系统库>编辑>已安装的jre>选择>编辑>并在jre home中尝试更改Java的较低版本，例如JRE home（C：\\ Program Files（x86）\\ Java \\ jre1.5.0_22 ），并将JRE命名为jre1.5.0_22，并很可能完成了已解决的问题
