Coveralls GitHub操作-错误：找不到Lcov文件

问题描述

我正在使用GitHub Action配置Coveralls。

我进行了搜索，但找不到如何生成./coverage/lcov.info文件。
当操作运行时，由于我没有这样的文件，所以我得到了

Using lcov file: ./coverage/lcov.info  
Error: Lcov file not found.

我尝试通过IntelliJ使用Coverage运行测试，但是我只能生成HTML格式的输出。

如何生成lcov.info文件？

解决方法

我在 GitHub Actions 上遇到了同样的错误（参见 this build log），但我有一个稍微不同的 GitHub Action workflow.yml（这在 Java/Maven 设置中可能更“默认”） :

name: build

on: [push]

jobs:
  coverage:
    runs-on: ubuntu-latest

    steps:
      - uses: actions/checkout@v2
      - uses: actions/setup-java@v1
        with:
          java-version: 15
      - run: mvn -B test -P coverage --no-transfer-progress

      - uses: coverallsapp/github-action@master
        with:
          github-token: ${{ secrets.GITHUB_TOKEN }}

并在我的 pom.xml 中为 jacoco-maven-plugin 和 coveralls-maven-plugin 提供以下配置：

<profiles>
    <profile>
        <id>coverage</id>
        <build>
            <plugins>
                <plugin>
                    <groupId>org.jacoco</groupId>
                    <artifactId>jacoco-maven-plugin</artifactId>
                    <version>${build-plugin.jacoco.version}</version>
                    <executions>
                        <!-- Prepares the property pointing to the JaCoCo
                        runtime agent which is passed as VM argument when Maven the Surefire plugin
                        is executed. -->
                        <execution>
                            <id>pre-unit-test</id>
                            <goals>
                                <goal>prepare-agent</goal>
                            </goals>
                        </execution>
                        <!-- Ensures that the code coverage report for
                        unit tests is created after unit tests have been run. -->
                        <execution>
                            <id>post-unit-test</id>
                            <phase>test</phase>
                            <goals>
                                <goal>report</goal>
                            </goals>
                        </execution>
                    </executions>
                </plugin>
                <plugin>
                    <groupId>org.eluder.coveralls</groupId>
                    <artifactId>coveralls-maven-plugin</artifactId>
                    <version>${build-plugin.coveralls.version}</version>
                </plugin>
            </plugins>
        </build>
    </profile>
</profiles>

在深入研究该主题后，我发现了 coverallsapp/github-action 中的 this issue，其中基本上说现在没有对 JaCoCo 与 Coveralls Action 的支持。

因此，除了切换到 https://codecov.io 和匹配的 https://github.com/codecov/codecov-action（如 the cucumber-jvm Team also did）之外，我没有其他选择。我们可以从 coveralls-maven-plugin 中删除 pom.xml。我的 workflow.yml 现在看起来像这样：

name: build

on: [push]

jobs:
  coverage:
    runs-on: ubuntu-latest

    steps:
      - uses: actions/checkout@v2
      - uses: actions/setup-java@v1
        with:
          java-version: 15
      - run: mvn -B test -P coverage --no-transfer-progress

      - uses: codecov/codecov-action@v1
        with:
          file: ./**/target/site/jacoco/jacoco.xml
          name: codecov

这里还有一个完全可以理解的示例项目：https://github.com/codecentric/cxf-spring-boot-starter/blob/master/.github/workflows/build.yml 我现在成功地使用了 codegov。

今天，相同的配置仍然有效，我想在GitHub端进行了一些更改。
