4.1

Changelog

After updating to this release, please repin any of your lock files, as the format of this file has changed slightly. This can be done using bazel run @unpinned_maven//:pin. Not repinning isn't an error, but you may see some warnings during the build.

New features

• @shs96c added maven_install.fail_if_repin_required which optionally allows builds to fail if the list of maven dependencies has changed but the lock file has not been regenerated (#509)
• @shs96c added a deploy_env attribute to java_export, which behaves similarly to the one in java_binary (#534)
• The REPIN environment variable used when repinning deps is also used by other rulesets, such as rules_rust. @gibfahn added RULES_JVM_EXTERNAL_REPIN to allow only repinning the java deps (#555)

Bug fixes

• @dhalperi updated bazel run @maven//:outdated, which is used to list artifacts that could be updated, by handling the case where artifact metadata is missing a release or latest tag (#508)
• @shs96c added code to generate pseudo-compile jars for downloaded dependencies. This should stop warnings about bad path element appearing during compilation (#518)
• @cheister fixed proxy parsing when the HTTP_PROXY environment variable doesn't have a scheme (#541) (#542)
• @sitaktif noted that symlinks don't work well when using a Remote Build Environment. They replace symlinks in maven_publish's DefaultInfo (#552)
• @cheister fixed the stamp_enabled flag so it continues to work as expected (#543)

Project health

• @shs96c made documentation bzl_library publicly visible. Rules that depend on rules_jvm_external can now be documented with stardoc (#527)
• @Bencodes updated jetifier to 1.0.0-beta10 (#548)
• @illicitonion updated the logic for telling users where to place their lock files (#558)

Usage

In your WORKSPACE file, add:

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

RULES_JVM_EXTERNAL_TAG = "4.1"
RULES_JVM_EXTERNAL_SHA = "f36441aa876c4f6427bfb2d1f2d723b48e9d930b62662bf723ddfb8fc80f0140"

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//:repositories.bzl", "rules_jvm_external_deps")

rules_jvm_external_deps()

load("@rules_jvm_external//:setup.bzl", "rules_jvm_external_setup")
