Ant: Add path to a java class inside a bash script

Question

I have an ant project in a directory which has 2 directories: bin and src and two files build.xml and script.sh.

The script.sh has the command:

time java SomeTestClass

where SomeTestClass is a class in bin. The bash script is executed in build.xml using the following:

<target name="run">
    <exec executable="/bin/bash">
            <arg value="script.sh"/>
    </exec>
</target>

However when I build using ant I get an error:

[exec] Error: Could not find or load main class SomeTestClass

How can I have the bash script see the java class SomeTestClass? I tried adding ./bin/SomeTestClass in the bash script, but the error changed to:

Error: Could not find or load main class ..bin.SomeTestClass

what happens if you run the script from commandline like `./script.sh` ? — Nikita Skvortsov, Apr 06 '17 at 06:29

The issue is in calling SomeTestClass. Several options here:

You must ensure that you add the location of your .class file to your classpath. So, if its in the current folder then add . to your classpath
If the class is in a package thepackagename - it must be called with its fully-qualified name:

java -classpath . thepackagename.TheClassName Please, read the fcomplete guide: Error: Could not find or load main class
