Re: Install Error

I have run into strange build errors with ant, only when I use the one that came with Linux. The problem is that it isn't using the correct version of java. You can display your version with something like...

<echo message="Using Java Version ${java.version} For Compilation"/>

in your build script. When you install a new version of ant it should pick up JAVA_HOME, but when you use the one that came with the system you might see something like:

[echo] Using Java Version 3.5-tree-ssa For Compilation

If you ever see this version of Java, you can probably expect strange results.
That might explain things.

For what it is worth, I downloaded a newer version of ant from apache. I spent about 3 hours trying to get ant to work without giving me a

Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/tools/ant/launch/Launcher

error.  Finally, I tried doing the following command:

java -jar <path_to_new_apache_and>/lib/ant-launcher.jar idvjar

And it worked!!!

Sorry for the wasted bandwidth, but thanks for the help!

Given the location (end of line) of the error, is it possible that Kevin is building on a Linux/Unix system and that this file has a DOS-like ending?

Although the error shows:

my first several lines from ViewManager.java are:

Hello,

I had to recompile my idv and came across the same errors that I reported back in May. Specifically, many lines similar to the following:

Hi Kevin,
It looks like somehow the source code in that file got corrupted. From the src jar on the ftp site we have:

harpo.unidata.ucar.edu: more ViewDescriptor.java

Why don't you try and download it and build again?
