Crash Reading 101

So I herd you liek crashing? Well good! I am here to help to fix those pesky crashes! Welcome to Crash Reading 101. A "crash" course! Minecraft runs very specifically especially when installing mods and the smallest error as you know can cause the mod to crash! >:( but do not fret! I am here to help! Let's start. Here I have gathered a bunch of crashes around the Pixelmon forum and compiled them into one universal tutorial anyone can understand!

Crash reports

The following messages are found under the section that says description near the top of the report.

---

• "java.lang.IllegalStateException: cannot determine the type of the type parameter 'REQ': class cpw.mods.fml.common.network.simpleimpl.SimpleChannelHandlerWrapper"
• "java.lang.NoClassDefFoundError: net/minecraftforge/common/util/EnumHelper"
• "java.lang.NoSuchMethodError: net.minecraft.client.gui.ScaledResolution.<init>"

All three of these errors occur with different incorrect versions of Forge installed. Make sure you are running the right 1.7.2 versions of Forge. You can find the proper version of Forge needed for Pixelmon on the Pixelmon download page.

---

• "cpw.mods.fml.common.LoaderException: java.lang.ClassNotFoundException: com.pixelmonmod.pixelmon.Pixelmon"

Do not extract the Pixelmon file. Place the entire downloaded file directly into the mods folder.

---

• "java.lang.NoClassDefFoundError: cpw/mods/fml/common/ICraftingHandler"

You are trying to run Pixelmon 3.0.4 with Minecraft 1.7.2, which will not work. Either update Pixelmon to 3.1 or downgrade Minecraft and Forge to 1.6.4.

---

• "java.lang.RuntimeException: Unknown character ' ' in"

Delete your Pixelmon.cfg file.

---

8"at cpw.mods.fml.common.Loader.preinitializeMods(Loader.java:506)" You have more than one version of Pixelmon in the mods folder. Only one version of Pixelmon should be in the mods folder at once.

---

• "at net.minecraft.server.MinecraftServer.<init>(MinecraftServer.java:140)"

Add "-Djava.net.preferIPv4Stack=true" to your VM args in the profile you are using. This is found on the Minecraft launcher.

Other

• "Java Version: 1.6.0_65"

If this shows up in your system details of the Minecraft crash report, you are running the wrong Java and several issues may occur in battle, such as priority and stat boosts becoming negative. Update your Java to 1.7.

If your crash report doesn't match any of these issues, post the full report in the [ttp://forum.pixelmonmod.com/tracker.php?p=4 Support Tracker].

I will add more as I find more posts on the forums ^_^ happy crashing. I think...
