无法在 CircleCI 上本地安装 Selenium

Question

我想在应用程序中使用 Selenium，但我在使用 CircleCI 时遇到了一些问题。

我在 lib/ 文件夹中有 3 个 jar 文件：client-combined-3.14.0.jar、htmlunit-driver-2.32.1-jar-with-dependencies.jar 和 core.jar .

前两个 jar 用于 Selenium 库，第三个是用于控制的处理语言核心 jar。

这是我的.circleci/config.yml:

version: 2
jobs:
  build:
    docker:
      # specify the version you desire here
      - image: circleci/openjdk:8-jdk

      # Specify service dependencies here if necessary
      # CircleCI maintains a library of pre-built images
      # documented at https://circleci.com/docs/2.0/circleci-images/
      # - image: circleci/postgres:9.4
    branches:
      only:
        - develop

    working_directory: ~/repo

    environment:
      # Customize the JVM maximum heap limit
      MAVEN_OPTS: -Xmx3200m

    steps:
      - checkout

      # installing packages
      - run: mvn install:install-file -Dfile="lib/client-combined-3.14.0.jar" -DgroupId="com.openqa" -DartifactId="selenium" -Dversion="3.14.0" -Dpackaging=jar -DgeneratePom=true
      - run: mvn install:install-file -Dfile="lib/htmlunit-driver-2.32.1-jar-with-dependencies.jar" -DgroupId="com.openqa.selenium" -DartifactId="htmlunit" -Dversion="2.32.1" -Dpackaging=jar -DgeneratePom=true
      - run: mvn install:install-file -DgroupId="processing" -DartifactId="core" -Dversion="3.3.7" -Dpackaging=jar -Dfile="lib/core.jar" -DgeneratePom=true

      # run tests!
      - run: echo "Testing"
      - run: mvn test

这是我的 pom.xml:

</project>

在 CircleCI 上，所有 3 个 jar 都已正确安装。更具体地说，这是 mvn install 为运行时的消息部分（上面只是从 maven 存储库下载的一堆）：

[INFO] Installing /home/circleci/repo/lib/client-combined-3.14.0.jar to /home/circleci/.m2/repository/com/openqa/selenium/3.14.0/selenium-3.14.0.jar

这是安装受控处理 jar 时的消息部分：

[INFO]

[INFO] Total time: 0.472 s
[INFO] Finished at: 2018-08-18T23:00:18Z
[INFO] ------------------------------------------------------------------------

但是，当mvn test为运行时，出现这个错误：

[ERROR] Failed to execute goal on project niche-finder: Could not resolve dependencies for project com.157239n:niche-finder:jar:1.0-SNAPSHOT: The following artifacts could not be resolved: org.openqa:selenium:jar:3.14.0, org.openqa.selenium:htmlunit:jar:2.32.1: Could not find artifact org.openqa:selenium:jar:3.14.0 in central (https://repo.maven.apache.org/maven2) -> [Help 1]

看来 2 个 selenium jar 没有正确安装，但 Processing jar 安装得很好。

那么这是 Selenium 方面的错误吗？或者我做错了什么？

请注意，目前我只想解决 Selenium 中的依赖关系，而不是运行在 CircleCI 上安装 Selenium 服务器。

Answer 1

我尽量不依赖从 https://www.seleniumhq.org/ and use the repository directly from this and this from the maven repository at https://mvnrepository.com/artifact/org.seleniumhq.selenium

下载的 jar 文件

那我干脆不安装本地的jar文件，只安装受控的core.jar，把我的pom.xml的一部分改成

<dependency>
    <groupId>org.seleniumhq.selenium</groupId>
    <artifactId>selenium-java</artifactId>
    <version>3.14.0</version>
</dependency>

<dependency>
    <groupId>org.seleniumhq.selenium</groupId>
    <artifactId>selenium-htmlunit-driver</artifactId>
    <version>2.52.0</version>
</dependency>

然后一切都构建得很好。
