无法构建bazel项目:没有这样的包@io_bazel_rules_kotlin//kotlin‘

Question

操作系统：

daz@daz:/rom/aosp-mirror/android-test$ uname -ar
Linux daz 5.4.0-28-generic #32-Ubuntu SMP Wed Apr 22 17:40:10 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux

使用bazel-2.2.0构建下面代码中的目标：

daz@daz:/rom/aosp-mirror/android-test$ bazel-2.2.0 build :axt_m2repository

我试图在这里构建android测试回购系统：

https://github.com/android/android-test

这些规则的定义似乎如下：

# Kotlin toolchains
rules_kotlin_version = "4c71740a1b63b785fc90afd8d4d4d5bfda527107"
http_archive(
    name = "io_bazel_rules_kotlin",
    sha256 = "c0ca7b66d9f466067635482592634703bf0a648d51ec958f41796d43ca8256b3",
    strip_prefix = "rules_kotlin-%s" % rules_kotlin_version,
    type = "zip",
    urls = ["https://github.com/bazelbuild/rules_kotlin/archive/%s.zip" % rules_kotlin_version],
)
load("@io_bazel_rules_kotlin//kotlin:kotlin.bzl", "kotlin_repositories", "kt_register_toolchains")
kotlin_repositories()
kt_register_toolchains()

但是，在尝试构建时，我会得到以下例外：

ERROR: error loading package '': Encountered error while reading extension file 'kotlin/kotlin.bzl': no such package '@io_bazel_rules_kotlin//kotlin': error loading package 'external': Could not load //external package

全部输出如下：

解决方案

建立分支机构：

androidx-test-1.3.0-beta01

使用bazel-2.2.0

bazel-2.2.0 build :axt_m2repository

这是android测试github问题跟踪器中的相关问题：

Answer 1

确保您使用的是最新版本的Bazel和android-test回购。

maven_jar本机规则在Bazel2.0 (巴泽尔追踪票)中被删除。您是否尝试过使用Bazel版本< 2.0 (例如1.2.1)来构建？
