bazel - extra_actions 之间的信息传递

Question

我有一个action_listener：

action_listener(
    name = "foo_listen",
    mnemonics = [
        "Foo", # Foo might usually take several minutes
    ],
    extra_actions = [
        "foo_action_pre", # Start some processing
        "foo_action_post", # Finish parts of processing that needs action output
    ],
)

在foo_action_pre中，我设置

out_templates=[
    "foo_action_pre_data",
],

以便将信息传递给foo_action_post.

现在，当我添加$(location foo_action_pre_data)到Bazelcmd的foo_action_post抱怨中时，它不是先决条件。

无论我是否添加它tools，data它都不会被检测为先决条件。如何声明正确的依赖关系？

Answer 1

您必须使用$(output foo_action_pre_data)而不是$(location foo_action_pre_data).

请参阅extra_action.cmd。
