Eclipse and Ant

[rdcarvallo]

Hi,
 I posted this on Newless Clewbies..but didn't get answers..  :-/
  
  I'm using Eclipse 2.1. My problem is that the Ant Builder included doesn't find the java executables,  i.e., I cannot use the <rmic ... > tag. To solve the problem I'm using  <exec ...jdk\bin\rmic.exe ..>
  I didn't try the others executables (jar, javac) because I 'm using the Ant script after Eclipse's Java build.
 When I try to build the project, I recieve the following error:

[rmic] BUILD FAILED: file:E:/Proyectos/jinitest/build.xml:4: Cannot use SUN rmic, as it is not available.  A common solution is to set the environment variable JAVA_HOME or CLASSPATH.
 

  I don't know if it's a problem of Eclipse(config or installation) or my Java installation.. (currently using j2sdk1.4.0 on Win98SE)
 
  Anyone knows where to configure correctly Ant in Eclipse??

what happens when you open a dos prompt and type "echo %JAVA_HOME%"?

If nothing, open up autoexec.bat and add

set JAVA_HOME=C:\path\to\java

the path being the root home of Java, something like C:\j2sdk1.4.0

near the top, there may be other "set" statements, place it by them.

Reboot your computer and see if that helps.

I tried that, my autoexec has the lines:

set JAVA_HOME=c:\jdk
set PATH=c:\jdk\bin;....


Both doesn't fix the problem.

Go to window-> preferences. Select the Ant section, runtime is under ant. Set ANT_HOME here.

[rdcarvallo]

What do I put there
It ask for a directory with a  lib directory inside...
Since Ant came with eclipse, I looked in the plugins directory, and found this..

C:\eclipse\plugins\org.eclipse.ant.core_2.1.0
C:\eclipse\plugins\org.apache.ant_1.5.2

The first one has a lib directory inside... tried setting it but still doesn't work..

I downloaded and installed ant from jakarta, then pointed to this in eclipse. Never tried eclipses own ant.

Still doesn't work... :-/
Following your tip, I downloaded Ant (1.5.3) and pointed in the ANT_HOME field in the preferences..
I also changed my autoexec to try Ant from the command line. Now it looks like:

set JAVA_HOME=c:\jdk
set ANT_HOME=c:\ant
set PATH=c:\jdk\bin;c:\ant\bin; ....

Next tested Ant from the command line and worked ok .
But in eclipse appears an error:

BUILD FAILED: java.lang.VerifyError: (class: org/apache/xerces/parsers/IntegratedParserConfiguration, method: configurePipeline signature: ()V) Incompatible type for getting or setting field

I don't want to open a D.O.S. window each time I need to rebuild my project..

What could be the error now?

I don't suppose that you looked at the Eclipse newsgroups.  For example,

  http://dev.eclipse.org/newslists/news.eclipse.tools/msg15225.html

Make sure that you have a username / password for the newsgroups as seen here:

  http://www.eclipse.org/newsgroups/index.html

Typically if you have problems with a third party tool the best place to get answers about that tool is forums, newsgroups, mailing lists, etc for that tool.
