修复问题 #1648
问题本质原因分析如下:
如上代码在高版本 gradle 配合 agp 中输出:
低版本中没问题,分析发现,高低版本 gradle 依赖的 groovy 版本不一样。
低版本:
groovy.util.XmlParser 内部对应 groovy.xml.QName
groovy.xml.Namespace 内部对应 groovy.xml.QName
所以从 application.attributes() 的 map 中通过 QName key 去获取是可以找到对应 hashkey 的 value。
高版本:
groovy.util.XmlParser 内部对应 groovy.xml.QName
groovy.xml.Namespace 内部对应 groovy.namespace.QName
所以从 application.attributes() 的 map 中通过 QName key 去获取是无法找到对应 hashkey 的 value,因为类名 QName 相同,但是 package name 已经不同了,导致 equals 方法无法相等,除非 XmlParser 也使用 groovy.xml 包下的,但是高版本 groovy 才有这个。
因此修复方案换成 XmlSlurper 即可兼容高低不同版本 groovy。
