Hi all,

First of all, thank you, Andy, for this book. It’s been a lot of fun.

Sorry if I do this wrong. This is my first post to this forum.

I’ve looked through this forum and can’t seem to find anyone else with this issue. The craftbukkit server works fine. But, when trying to build the HelloWorld plugin, I get an ‘error in opening zip file’ error and compilation stops. Here’s what I copied from the shell:



C:\Users\D\Desktop>C:\Windows\system32\cmd.exe /c sh.exe -l
~ $ cd Desktop
~/Desktop $ cd code/HelloWorld
~/Desktop/code/HelloWorld $ ls
bin         build.sh    dist        plugin.yml  src
~/Desktop/code/HelloWorld $ ./build.sh
Compiling with javac...
error: error reading C:\Users\D\Desktop\server\bukkit.jar; error in opening zip file
warning: [options] bootstrap class path not set in conjunction with -source 1.6
1 error
1 warning
~/Desktop/code/HelloWorld $


I’m running Windows 8.1.

Thank you for your help!

David

When I run: javac -version

I get: javac 1.8.0_05

And when I run: java -version

I get: java version “1.8.0_05”

So, I’m thinking maybe it’s a problem with the -source and the -target both being set to 1.6 ??

I’ll try setting to 1.8 and post what happens…

Thanks! David

Okay changing the build.sh file so that -source and -target are set to 1.8 didn’t get rid of the error, but it did get rid of the warning listed in my first post. Weird…

Here’s the code from build.sh:


# 1. Compile
echo "Compiling with javac..."
javac -Xlint:deprecation src/*/*.java -d bin -classpath "$BUKKIT" -sourcepath src -target 1.8 -g:lines,vars,source -source 1.8 || exit 2

Okay, I tried setting source and target to 1.7. The error remained, and it brought back the ‘bootstrap’ warning…

Any help would be much appreciated :)

Could be a corrupted jar file, I suppose. Make sure it downloaded ok. Also, the JAVA_HOME setting could be wrong. Make sure that it points to the root of the Java JDK (not the JRE, which doesn’t have the development tools). So it should be set to something like C:\Program Files (x86)\Java\jdk1.6.0_15

Thank you, Andy!

I created a JAVA_HOME environment variable and pointed it at my jdk folder. But that didn’t fix it.

Then, I deleted the bukkit.jar file from the server directory, re-downloaded it from the BukkitWikki page into the server directory (renamed it to bukkit.jar during the download), and it worked! Thanks so much! :)

Ah, so it was corrupted somehow. The simplest explanation is usually the right one!

Yes. Definitely another learning experience. :)
