Description
When running EasyAnt with J2SE 1.7, calling EasyAntEngine.guessEasyantCoreJarUrl() raises a NoSuchMethodException/IllegalArgumentException.
Code to fix:
EasyAntEngine.getLocalURL = conn.getClass().getMethod("getLocalURL", (Class<?>) null)
URL localJarUrl = (URL) getLocalURL.invoke(conn, (Class<?>) null)
Fixed code:
EasyAntEngine.getLocalURL = conn.getClass().getMethod("getLocalURL", null)
URL localJarUrl = (URL) getLocalURL.invoke(conn, null)
Reason:
From JES2 1.7 Javadoc, calling getMethod or invoke with no varArg or a null varArg is treated as if the method was called with an empty array (compliance with JES2 1.5).
But calling those methods with a null varArg that is casted to Class<?> is treated as an array of Class<?> that contains one null element. So there is no matching method, hence the NoSuchMethodException/IllegalArgumentException.
