Dear All,
I'd like to install DSpace to check whether we can use it for our
planned OA-Repository. But reaching the point to say 'ant fresh_install'
I get the following error message where I can not figure out the reason:
Buildfile: build.xml
compile:

build_wars:

BUILD FAILED
/opt/dspace-1.4.2-source/build.xml:293: Java returned: 1
Total time: 3 seconds
Any suggestions? I think its not directly a problem with dspace, but
with my Java installation. But anyway I would be glad for any hint.
Here some info about my environment:
>uname -a
Linux OSU458 2.6.20-16-generic #2 SMP Sun Sep 23 19:50:39 UTC 2007 i686
GNU/Linux
(in fact it's an Ubuntu 7.04)
>javac -version
Eclipse Java Compiler v_686_R32x, 3.2.2 release, Copyright IBM Corp
2000, 2006. All rights reserved.
>java -version
java version "1.5.0_11"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_11-b03)
Java HotSpot(TM) Server VM (build 1.5.0_11-b03, mixed mode)
>echo $JAVA_HOME
/usr/lib/jvm/java-1.5.0-sun
>psql --version
psql (PostgreSQL) 8.2.5
Further I installed Tomcat 5.5.25 successfully.
Best regards
Robert
