groovy:：component if语句的计算结果不为true

您好，我正在试图了解给定的

如果（版本存在！=''&&env.force\u build==true）

计算为true的问题，即使env.force\u build设置为false

env.force\u build

像布尔值一样打印，但它是一个字符串

"false" == true
// → false
"false" == false
// → false

始终使用适当的工具调试此类问题。使用

.inspect（）

或者甚至

.dump（）

要了解您手头的数据类型：

"false".inspect()
// → 'false'
"false".dump()
// → <java.lang.String@5cb1923 value=[102, 97, 108, 115, 101] coder=0 hash=97196323>

"false".toBoolean() == true
// → false
"false".toBoolean() == false
// → true
