我正在尝试在使用sbt 0.13.13时删除此设置的弃用警告
task <<=
(streams in Test,
loadedTestFrameworks in Test,
testLoader in Test,
testGrouping in Test in test,
testExecution in Test in task,
fullClasspath in Test in test,
javaHome in test) flatMap Defaults.allTestGroupsTask
warning: `<<=` operator is deprecated.
Use `key := { x.value }` or `key ~= (old => { newValue })`.
See http://www.scala-sbt.org/0.13/docs/Migrating-from-sbt-012x.html
<<=
运算符现已弃用,但我不知道如何重写上面的表达式。
我试图将其重写为:
task := Defaults.allTestGroupsTask(
(streams in Test).value,
(loadedTestFrameworks in Test).value,
(testLoader in Test).value,
(testGrouping in Test in test).value,
(testExecution in Test in task).value,
(fullClasspath in Test in test).value,
(javaHome in test).value)
但我无法使用Task[A]
TaskKey
分配给:=
我应该怎么做才能删除<<=
呢?
答案 0 :(得分:1)
尝试使用Def.taskDyn
:
task := Def.task {
Def.task {
Defaults.allTestGroupsTask(
(streams in Test).value,
(loadedTestFrameworks in Test).value,
(testLoader in Test).value,
(testGrouping in Test in test).value,
(testExecution in Test in task).value,
(fullClasspath in Test in test).value,
(javaHome in test).value
)
}.value
}.value
