I'm trying to install Apache Ivy, but I can't get ant to recognize it.
Per Apache Ivy installation instructions, I downloaded Ivy from osuosl.org Ivy archives, unpacked it, and copied the .jar file to where ant should be able to see it. However, any ivy-dependent build I attempt fails as follows:
$ ant Buildfile: /home/ec2-user/ivy/apache-ivy-2.3.0/build.xml init-ivy: [taskdef] Could not load definitions from resource org/apache/ivy/ant/antlib.xml. It could not be found. retrieve-all: BUILD FAILED /home/ec2-user/ivy/apache-ivy-2.3.0/build.xml:55: Problem: failed to create task or type antlib:org.apache.ivy.ant:retrieve Cause: The name is undefined. Action: Check the spelling. Action: Check that any custom tasks/types have been declared. Action: Check that any <presetdef>/<macrodef> declarations have taken place. No types or tasks have been defined in this namespace yet This appears to be an antlib declaration. Action: Check that the implementing library exists in one of: -/usr/share/ant/lib -/home/ec2-user/.ant/lib -a directory added on the command line with the -lib argument
I've hunted around, and every page I look at seems to agree that I just need to "install the Ivy jar file", but this doesn't seem to help. I've tried:
- Copying ivy-2.3.0.jar into /usr/share/ant/lib and/or ~/.ant/lib
- The same, but renaming it ivy.jar
-lib /path/to/ivy-2.3.0.jarto the ant command
- All of this in the ivy directory or the src/example/hello-ivy directory
Interestingly, in the src/example/go-ivy directory, executing
ant succeeds; but that doesn't help other ivy-based builds to run.
I must be missing something excruciatingly obvious, but I can't see what it is. Any ideas?
