2.10

Changelog

• Added a migration tool to convert maven_jar usages to maven_install. See announcement and usage instructions.
• Bazel can now provide helpful buildozer add dep messages when referencing a class not provided through a direct JAR dependency. This is a feature of Bazel's strict Java dependency compiler plugin, where referenced classes from transitive targets need to be declared as direct dependencies. For example:

$ bazel build //:B_no_dep

...

B.java:6: error: [strict] Using type com.google.common.collect.Lists from an indirect dependency (TOOL_INFO: "@maven//:com_google_guava_guava"). See command below **
        System.err.println(Lists.reverse(A.INTEGERS));
                           ^
 ** Please add the following dependencies:
  @maven//:com_google_guava_guava to //:B_no_dep
 ** You can use the following buildozer command:
buildozer 'add deps @maven//:com_google_guava_guava' //:B_no_dep

...

Usage

In your WORKSPACE file, add:

load("@bazel_tools//tools/build_defs/repo:http.bzl", "http_archive")

RULES_JVM_EXTERNAL_TAG = "2.10"
RULES_JVM_EXTERNAL_SHA = "1bbf2e48d07686707dd85357e9a94da775e1dbd7c464272b3664283c9c716d26"

http_archive(
    name = "rules_jvm_external",
    strip_prefix = "rules_jvm_external-%s" % RULES_JVM_EXTERNAL_TAG,
    sha256 = RULES_JVM_EXTERNAL_SHA,
    url = "https://github.com/bazelbuild/rules_jvm_external/archive/%s.zip" % RULES_JVM_EXTERNAL_TAG,
)

load("@rules_jvm_external//:defs.bzl", "maven_install")

maven_install(
    artifacts = [
        "junit:junit:4.12",
        "androidx.test.espresso:espresso-core:3.1.1",
        "org.hamcrest:hamcrest-library:1.3",
    ],
    repositories = [
        "https://jcenter.bintray.com/",
        "https://maven.google.com",
        "https://repo1.maven.org/maven2",
    ],
)

In your BUILD file, reference the targets directly:

java_library(
    name = "java_test_deps",
    exports = [
        "@maven//:junit_junit"
        "@maven//:org_hamcrest_hamcrest_library",
    ],
)

android_library(
    name = "android_test_deps",
    exports = [
        "@maven//:junit_junit"
        "@maven//:androidx_test_espresso_espresso_core",
    ],
)
