Description
As part of GROOVY-8520, I'm trying to implement the CliBuilder.parseFromSpec(Class, String[]) method. The implementation of this method populates a Map with data from the command line, and returns this map, coerced to the specified interface type.
This should work, but the CliBuilderTest.testParseFromSpec and testParseFromInstanceFlagEdgeCases tests fail with an error:
groovy.lang.MissingMethodException: No signature of method: java.util.LinkedHashMap.first() is applicable for argument types: () values: [] Possible solutions: print(java.lang.Object), print(java.io.PrintWriter), find(), sort(), is(java.lang.Object), find(groovy.lang.Closure)
Here is a minimal class that reproduces the issue:
class CoercionTest extends GroovyTestCase { void testCoercion() { def spec = parseFromSpec(MySpec, []) assert spec.foo() == 'firstval' } interface MySpec { String foo(); } public <T> T parseFromSpec(Class<T> optionsClass, args) { def cliOptions = [:] cliOptions['foo'] = 'firstval' cliOptions as T } }
This gives:
groovy.lang.MissingMethodException: No signature of method: java.util.LinkedHashMap.foo() is applicable for argument types: () values: [] Possible solutions: sort(), any(), find(), get(java.lang.Object), get(java.lang.Object), get(java.lang.Object) at org.codehaus.groovy.runtime.ScriptBytecodeAdapter.unwrap(ScriptBytecodeAdapter.java:72) at org.codehaus.groovy.runtime.callsite.PojoMetaClassSite.call(PojoMetaClassSite.java:48) at org.codehaus.groovy.runtime.callsite.CallSiteArray.defaultCall(CallSiteArray.java:47) at org.codehaus.groovy.runtime.callsite.AbstractCallSite.call(AbstractCallSite.java:116) at org.codehaus.groovy.runtime.callsite.AbstractCallSite.call(AbstractCallSite.java:120) at some.pkg.CoercionTest.testCoercion(CoercionTest.groovy:7)
I'm probably doing something wrong, but can't figure out what... Any hints?
