maven(15)------maven打包时报错Fatal error compiling: 无效的目标发行版: 1.8.0_91
对于刚接触maven的朋友,喜欢兴冲冲的从官网下载一个maven,开始构建maven项目,
等使用maven打包的时候,出现如下错误:
[WARNING] The requested profile "jdk-1.8" could not be activated because it does not exist.
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.1:
compile (default-compile) on project springboot: Fatal error compiling: 无效的目标发行版: 1.8.0_91 -> [Help 1]
[ERROR]
[ERROR] To see the full stack trace of the errors, re-run Maven with the -e switch.
[ERROR] Re-run Maven using the -X switch to enable full debug logging.

[ERROR] For more information about the errors and possible solutions, please read the following articles:

出现这个问题的最好解决办法就是在maven下setting.xml中的profiles元素中增加如下配置:
<profile> <id>jdk-1.8</id> <activation> <activeByDefault>true</activeByDefault> <jdk>1.8</jdk> </activation> <properties> <maven.compiler.source>1.8</maven.compiler.source> <maven.compiler.target>1.8</maven.compiler.target> <maven.compiler.compilerVersion>1.8</maven.compiler.compilerVersion> </properties> </profile>注意,根据你的jdk版本进行配置,这里使用的jdk8.
另外一种解决办法就是在pom.xml文件中显示指定jdk版本:
<build> <plugins> <!-- 编译插件 --> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-compiler-plugin</artifactId> <version>3.1</version> <configuration> <source>1.8</source> <target>1.8</target> <encoding>UTF-8</encoding> </configuration> </plugin> </plugins> </build>如果采用以上某个解决方案还是出现同样的问题,哪就是项目编译设置问题:
选中项目-->“右键”-->"Properties"-->"Java Build Path"-->"JRE System Library..."-->"Edit"选择你安装的jdk:
如果还有问题,可能就是java环境变量没配置好,
或者maven中配置的jdk版本与java环境变量配置的版本不一致!
