Question

当我使用此命令编译Java项目时：

mvn install

抛出此错误：

    [INFO] Changes detected - recompiling the module!

这是我的编译项目pom.xml配置：

 <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-compiler-plugin</artifactId>
                <version>3.7.0</version>
                <configuration>
                    <source>1.8</source>
                    <target>1.8</target>
                    <encoding>UTF-8</encoding>
                </configuration>
            </plugin>

这是我的操作系统和java环境信息：

[root@firewalld cqnews-online]# mvn -v

解决此问题的两个步骤：

更改为eclipse编译器
将版本升级到2.x +

这是配置：

           <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-compiler-plugin</artifactId>
                <version>3.7.0</version>
                <configuration>
                    <source>1.8</source>
                    <target>1.8</target>
                    <encoding>UTF-8</encoding>
                    <compilerId>eclipse</compilerId>
                </configuration>
                <dependencies>
                    <dependency>
                        <groupId>org.codehaus.plexus</groupId>
                        <artifactId>plexus-compiler-eclipse</artifactId>
                        <version>2.8.4</version>
                    </dependency>
                    <dependency>
                        <groupId>org.codehaus.plexus</groupId>
                        <artifactId>plexus-compiler-javac</artifactId>
                        <version>2.8.4</version>
                    </dependency>
                </dependencies>
            </plugin>
