[ant][eclipse][junit] fails to build

re: [ant][eclipse][junit] fails to build

Hi,

I made a sample set of classes and test classes, using old junit 3.8.1, on wsad 5.x.

Has anyone any idea on this?

  
Buildfile: C:\wd\junitInActionBook\code\ch5\build.xml
 
compile.java:
       [javac] Compiling 2 source files to C:\wd\junitInActionBook\code\ch5\target\classes\java
       [javac] Modern compiler not found - looking for classic compiler
       [javac] BUILD FAILED: file:C:/wd/junitInActionBook/code/ch5/build.xml:17: Cannot use classic compiler, as it is not available.  A common solution is to set the environment variable JAVA_HOME to your jdk directory.

Have you read the error message?

"A common solution is to set the environment variable JAVA_HOME to your jdk directory."

Not a testing question, moving...

I forgot to mention - JAVA_HOME is currently set to my JDK when I ran it.

Does JAVA_HOME have blanks in it? It might help to replace c:\Program Files by c:\progra~1.

No, it doesnt have any spaces. Any idea?

Jesus,

A little bit of googling the error description says that this could occur when tools.jar is not available on the classpath. When you invoke ant using ant.bat it automatically loads tools.jar and no need to manually include that in classpath.

Perhaps you could try and echo classpath and check.

<echo message="${java.class.path}" />

Let us know how it works.

Cnu.

I got

Thanks. It worked, using the tips in that webpage.

The error now is on the formatter for xml. For plain output, it is ok.

http://dev.eclipse.org/newslists/news.eclipse.tools/msg08430.html has a solution.

Are you using a non-standard ant version, or an older jdk?
These things seem to work out of the box when using standard ant download with 1.4+ JDKs.
