Example 56 with PropertyExpression

use of org.codehaus.groovy.ast.expr.PropertyExpression in project gradle by gradle.

the class GradleResolveVisitor method correctClassClassChain.

// iterate from the inner most to the outer and check for classes
// this check will ignore a .class property, for Example Integer.class will be
// a PropertyExpression with the ClassExpression of Integer as objectExpression
// and class as property
