【问题描述】：

我想生成 junit 的测试覆盖率报告。所以我使用了jacoco maven插件：

这里是我的 pom.xml

                                    </limits>
                                </rule>

                </executions>
            </plugin>
        </plugins>
    </build>

但是当我运行这个时：

mvn clean verify

我得到错误：

    【解决方案1】：

    你的输出是预期的。

    报告在文件夹target/site/jacoco 中生成。请参阅下面的 Maven 构建日志。

    [INFO] --- jacoco-maven-plugin:0.8.8:report (report) @ mymodule1 ---
[INFO] Loading execution data file /home/alexeij/dev/projects/JavaTestMavenBOM/mymodule1/target/jacoco.exec
[INFO] Analyzed bundle 'mymodule1' with 7 classes

    检查您的target/site/jacoco 文件夹，它应该类似于以下内容：

    target/site/jacoco/
├── index.html
├── io.sampadadubey.java.jacoco
│   ├── index.html
│   ├── index.source.html
│   ├── JacocoDemoApplication.html
│   └── JacocoDemoApplication.java.html
├── jacoco.csv
├── jacoco-resources
│   ├── branchfc.gif
│   ├── branchnc.gif
│   ├── branchpc.gif
│   ├── bundle.gif
│   ├── class.gif
│   ├── down.gif
│   ├── greenbar.gif
│   ├── group.gif
│   ├── method.gif
│   ├── package.gif
│   ├── prettify.css
│   ├── prettify.js
│   ├── redbar.gif

│   ├── report.gif
│   ├── session.gif
│   ├── sort.gif
│   ├── sort.js
│   ├── source.gif
│   └── up.gif
├── jacoco-sessions.html
└── jacoco.xml

    您的构建配置如下：

    1. 在initialize 阶段运行prepare-agent 目标。
    2. 在test 阶段运行report 目标。
    3. 在verify 阶段运行check 目标。

    您的构建在verify 阶段失败，因为不符合配置的check。来自check 目标的错误如下：

    Coverage checks have not been met. See log for details.

    这里是告诉你失败细节的日志。

    [INFO] --- jacoco-maven-plugin:0.8.8:check (jacoco-check) @ mymodule1 ---
[INFO] Loading execution data file /home/alexeij/dev/projects/JavaTestMavenBOM/mymodule1/target/jacoco.exec

[WARNING] Rule violated for package com.gmail.alexei28.javatestmavenbom.module1.ngnms: lines covered ratio is 0.00, but expected minimum is 0.50
[WARNING] Rule violated for package com.gmail.alexei28.javatestmavenbom.module1: lines covered ratio is 0.00, but expected minimum is 0.50

    使其更易于阅读。

    Rule violated for package com.gmail.alexei28.javatestmavenbom.module1.ngnms: lines covered
ratio is 0.00, but expected minimum is 0.50

Rule violated for package com.gmail.alexei28.javatestmavenbom.module1: lines covered
ratio is 0.00, but expected minimum is 0.50
