Bazel 宏失败并显示 `name 'glob' is not defined`

Question

我定义了一个 Bazel 宏。它看起来像这样：

def my_macro():
    java_binary(
        srcs = glob(["*.java"])
        # ...
    )

当我运行 Bazel 时，它因错误而失败

ERROR: /home/.../macros.bzl:105:19: name 'glob' is not defined

是否可以在宏中使用 glob？

Answer 1

glob function is only available in BUILD.bazel files. In macro definitions in a .bzl file, access it as native.glob.

def my_macro():
    java_binary(
        srcs = native.glob(["*.java"])
        # ...
    )

Bazel macro fails with `name 'glob' is not defined`
