Description

In the original state of the test_database target in build.xml, the classpath built within the task becomes too long to be properly handled by the <java> task that follows, which causes failure of any task that includes test_database. I fixed the task so that the classpath is stored in an alias that is then used in the <javac> task, which doesn't fail anymore.

Instructions for Reviewers

After building the project using Maven, run fresh_install (or any task that has test_database in its transitive dependencies) in /dspace/target/dspace-installer/build.xml.

List of changes in this PR:

• Fixed the test_database target in /dspace/target/dspace-installer/build.xml.

Please note that I am not sure whether this behaviour will be reproducible in all environments. I work in a Windows 10-based environment.

A 2kB CLASSPATH is not particularly long for a large project, alas! I got into a DSpace instance's 'lib/' directory and ran 'ls | wc'. That instance's 180 required JARs have names adding up to 4311 bytes (including space delimiters).
