Description

The current master branch of Grails won't compile with Java 1.7 . It compiles ok with Java 1.6 .

The error message is:

[ant:groovyc] /tmp/groovy-generated-614097634888075990-java-sourc
[ant:groovyc] e/org/codehaus/groovy/grails/cli/interactive/GrailsInteractiveCompletor.java:15: error: unreported exception IOException; must b
[ant:groovyc] e caught or declared to be thrown
[ant:groovyc] super ((java.io.InputStream)null);
[ant:groovyc]       ^

Reproducing error:

git clone https://github.com/grails/grails-core.git
cd grails-core
git checkout 1239b8ed
./gradlew clean compileGroovy

Generated stub with error:

}

However the stub is ok if I remove "groovyOptions.useAnt = true" and "options.useAnt = true" from the build.gradle of Grails:

package org.codehaus.groovy.grails.cli.interactive;

super ((java.lang.String)null);
}

public static  java.lang.String[] getScriptNames(java.util.List<java.io.File> scriptResources) { return (java.lang.String[])null;}
}

diff of generated stubs:

< super ((java.lang.String)null);

however the picked constructor in the successfull case is also invalid. The groovy source code is calling the constructor with the String[] constructor.
