参考：https://mp.weixin.qq.com/s/v0ihaPsuyGufdc_ImEqX8A给mybatis3源码加注释并编译源代码

编译命令：

mvn clean

mvn install -DskipTests=true -Dmaven.test.skip=true -Dlicense.skip=true

自己编译Mybatis3源码的时候报错如下：

解决办法：

将mybatis/pom.xml中以下依赖注释掉

<plugin>

  <groupId>org.apache.maven.plugins</groupId>

  <artifactId>maven-pdf-plugin</artifactId>

</plugin>

将mybatis-parent/pom.xml中以下依赖注释掉

<plugin>

  <groupId>org.apache.maven.plugins</groupId>

  <artifactId>maven-pdf-plugin</artifactId>

  <version>${pdf.version}</version>

  <executions>

    <execution>

      <id>pdf</id>

      <phase>prepare-package</phase>

      <goals>

        <goal>pdf</goal>

      </goals>

      <configuration>

        <includeReports>false</includeReports>

      </configuration>

    </execution>

  </executions>

</plugin>

注释掉上面依赖，重新编译即可。
