Groovy '；AST不可用'；筛选数据集时发生异常
我有以下groovy程序-Groovy '；AST不可用'；筛选数据集时发生异常,groovy,groovy-sql,Groovy,Groovy Sql,我有以下groovy程序- def people = sql.dataSet('players') def d = people.findAll { true } print d.rows() 我在print语句中遇到一个异常 groovy.lang.GroovyRuntimeException: DataSet unable to evaluate expression. AST not available for closure: in.kshitiz.pgnimport.dao.Play
def people = sql.dataSet('players')
def d = people.findAll { true }
print d.rows()
groovy.lang.GroovyRuntimeException: DataSet unable to evaluate expression. AST not available for closure: in.kshitiz.pgnimport.dao.PlayerDao$_get_closure1. Is the source code on the classpath?

这个例外没有多大帮助。这意味着什么？只需将groovy DAO源代码添加到类路径中即可解决问题 在邮件列表中，Guillaume Laforge说： Sql类的使用有一个转折点 它需要您的Groovy类源代码可用——比如在运行Groovy myScript.Groovy时 例如，当一个类被预编译时，“类节点”将不再可用，因为它不存储在字节码中 这可能是你在这里面临的问题 类节点对于
