Description Nadav Har'El 2020-07-19 14:37:29 UTC

In the open-source project git:scylladb/scylla-tools-java there is a build.xml for ant. If I try to run "ant" in that directory I get an error:

BUILD FAILED
/home/nyh/scylla.maintainer/tools/java/build.xml:159: java.lang.ClassNotFoundException: org.apache.bsf.engines.javascript.JavaScriptEngine
	at java.net.URLClassLoader.findClass(URLClassLoader.java:382)
	at java.lang.ClassLoader.loadClass(ClassLoader.java:418)
	at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:352)
	at java.lang.ClassLoader.loadClass(ClassLoader.java:351)
	at org.apache.bsf.BSFManager.loadScriptingEngine(BSFManager.java:696)
	at org.apache.bsf.BSFManager.exec(BSFManager.java:485)
	at org.apache.tools.ant.util.optional.ScriptRunner.executeScript(ScriptRunner.java:100)
...

Indeed this build.xml has a bunch of Javascript scripts in them, which it seems (I'm not an ant expert) aren't really used in a normal build, but is nevertheless there.

The really weird thing is that this this error message mentions "bsf", so I looked around and found that the "ant-apache-bsf" and "bsf" packages *are* installed on my system. But they don't include this missing JavaScriptEngine class in their jars. Ironically, the mere existence of these packages on my system is what causes these error messages: If I remove them (rpm -e --nodeps), either both of them or even just the "bsf" package, ant in that project begins to work again!

bsf is built without JavaScript support to reduce the number of dependencies it pulls in.
But if this breaks packages, we can reintroduce the rhino dependency to fix JavaScript support.
