我的直觉可能是正确的使用 Package 和/或分类器。为了找到构建文件的正确导入标记，我建议访问 .cache/bazel/bazel_user/.../external/maven/BUILD file 将文章编辑到工作设置中
我想使用bazel构建工具测试我自己的async flink stream操作符richayncFunction。
这与如何使用flink的testharness类基本相同？
主要的问题是我找不到进口 org.apache.flink.streaming.util.OneInputStreamOperatorTestHarness 以及测试蒸汽操作员所需的所有其他代码。
我试图遵循提供的答案，但我与bazel语法斗争，问自己是否有可能在bazel中使用这些导入。
我正在使用最新的bazel版本和intellij2019.3.4以及bazel插件。
链接的答案假设maven依赖：

<dependency>
    <groupId>org.apache.flink</groupId>
    <artifactId>flink-test-utils-junit</artifactId>
    <version>${flink.version}</version>
</dependency>

<dependency>
    <groupId>org.apache.flink</groupId>
    <artifactId>flink-streaming-java_2.11</artifactId>
    <version>${flink.version}</version>
    <scope>test</scope>
    <type>test-jar</type>
</dependency>

<dependency>
    <groupId>org.apache.flink</groupId>
    <artifactId>flink-runtime_2.11</artifactId>
    <version>${flink.version}</version>
    <scope>test</scope>
    <type>test-jar</type>
</dependency>

我的工作区是这样的

load("@maven//:compat.bzl", "compat_repositories")

compat_repositories()

测试maven安装“group”是我试图弄清楚如何导入所需的依赖项，因为据我所知，bazelmaven语法中没有显式的“type”和“scope”。
测试生成文件如下所示

load("@rules_java//java:defs.bzl", "java_test")
load("@rules_jvm_external//:specs.bzl", "maven")
load("@rules_jvm_external//:defs.bzl", "artifact", "maven_install")

java_test(
    name = "some_module",
    size = "medium",
    srcs = ["DataOperatorTests.java"],
    tags = [
        "docker",
        "integration",
    ],
    test_class = "org.some.project.DataOperatorTests",
    deps = [

        "@maven//:com_google_protobuf_protobuf_java",
        "@maven//:junit_junit_4_13",
        "@maven//:org_apache_flink_flink_connector_kafka_0_11_2_11",
        "@maven//:org_apache_flink_flink_core",
        "@maven//:org_apache_flink_flink_java",
        "@maven//:org_javatuples_javatuples",
        "@maven//:org_mongodb_bson",
        "@maven//:org_mongodb_mongodb_driver_core",
        "@maven//:org_mongodb_mongodb_driver_reactivestreams",
        "@maven//:org_testcontainers_kafka",
        "@maven//:org_testcontainers_testcontainers",
        "@maven//:org_apache_flink_flink_streaming_java_2_11",
        "@testing//:org_apache_flink_flink_runtime_2_11_tests",
        "@testing//:org_apache_flink_flink_streaming_java_2_11_tests",
        "@testing//:org_apache_flink_flink_test_utils_junit",
        "@testing//:org_apache_flink_flink_tests",
    ],
)

test_suite(name = "smoke",tags = ["-docker","-internal",],)

test_suite(name = "unit",tags = ["-internal","unit",],)

test_suite(name = "integration",tags = ["-internal","integration",],)

test_suite(name = "internal")

通过上述设置，以下错误不再发生-留作参考
这些包似乎存在，但在实际的测试构建文件中，我在同步过程中遇到了这个错误。

Error:(5, 1) no such target '@testing//:org_apache_flink_flink_streaming_java_2_11': target 'org_apache_flink_flink_streaming_java_2_11' not declared in package '' defined by /home/user/.cache/bazel/_bazel_user/7b62e4e31c70ee640c6d33972433da28/external/testing/BUILD and referenced by '//core/src/test/java/org/some/project/some_module:some_module'

我自己解决了这个问题。将上述代码调整为合适的解决方案。
总而言之。
当maven存储库是这样给出的：

<dependency>
    <groupId>org.apache.flink</groupId>
    <artifactId>flink-test-utils-junit</artifactId>
    <version>${flink.version}</version>
</dependency>

<dependency>
    <groupId>org.apache.flink</groupId>
    <artifactId>flink-streaming-java_2.11</artifactId>
    <version>${flink.version}</version>
    <scope>test</scope>
    <type>test-jar</type>
</dependency>

<dependency>
    <groupId>org.apache.flink</groupId>
    <artifactId>flink-runtime_2.11</artifactId>
    <version>${flink.version}</version>
    <scope>test</scope>
    <type>test-jar</type>
</dependency>

相应的bazel工作区文件必须包含如下条目：

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

maven_install(
    ...
    artifacts = [
        maven.artifact(
            group = "org.apache.flink",
            artifact = "flink-runtime_2.11",
            version = FLINK_VERSION,
            classifier = "tests",
            packaging = "test-jar",
        ),
        maven.artifact(
            group = "org.apache.flink",
            artifact = "flink-streaming-java_2.11",
            version = FLINK_VERSION,
            classifier = "tests",
            packaging = "test-jar",
        ),
        maven.artifact(
            group = "org.apache.flink",
            artifact = "flink-test-utils-junit",
            version = FLINK_VERSION,
        ),
        "org.apache.flink:flink-tests:%s" % FLINK_VERSION,
    ],
    repositories = [
        "https://jcenter.bintray.com/",
        "https://maven.google.com",
        "https://repo1.maven.org/maven2",
    ],
)

有关依赖关系的详细说明，请参见：https://github.com/bazelbuild/rules_jvm_external#detailed-依赖信息规范和此处：https://github.com/bazelbuild/rules_jvm_external/blob/master/docs/api.md#mavenartifact
要在构建文件中找到要导入的结果目标，请使用@jin提到的方法

bazel query @maven//:all | grep flink_flink_streaming

在大多数情况下，目标可能只有后缀 _tests 以下是生成文件的必要导入：

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

java_test(
    name = "some_module",
    size = "medium",
    srcs = ["DataOperatorTests.java"],
    tags = [
        "docker",
        "integration",
    ],
    test_class = "org.some.project.DataOperatorTests",
    deps = [
        ...
        "@maven//:org_apache_flink_flink_runtime_2_11_tests",
        "@maven//:org_apache_flink_flink_streaming_java_2_11_tests",
        "@maven//:org_apache_flink_flink_test_utils_junit",
        "@maven//:org_apache_flink_flink_tests",
    ],
