(default-compile) on project app: Fatal error compiling: 无效的标记: --release -> [Help 1]

 

<plugins>
  <plugin>
    <artifactId>maven-compiler-plugin</artifactId>
    <version>${maven-compiler-plugin.version}</version>
    <configuration>
      <release>8</release>
    </configuration>
  </plugin>
</plugins>

如果你的pom.xml文件如上所示，并且使用jdk8,则会报错

(default-compile) on project app: Fatal error compiling: 无效的标记: --release -> [Help 1]

 

查阅官方文档，release Java9才支持

 

http://maven.apache.org/plugins/maven-compiler-plugin/compile-mojo.html#release

<release>

The -release argument for the Java compiler, supported since Java9

• Type: java.lang.String
• Since: 3.6
• Required: No
• User Property: maven.compiler.release

 

 

解决办法，可以设计jdk版本到Java9+，或者更改maven-compiler-plugin配置

参考如下

<configuration>
  <source>${maven.compiler.source}</source>
  <target>${maven.compiler.target}</target>
  <compilerArguments>
    <bootclasspath>${java.home}/lib/rt.jar</bootclasspath>
  </compilerArguments>
  <encoding>${project.build.sourceEncoding}</encoding>
  <annotationProcessorPaths>
    <path>
      <groupId>org.projectlombok</groupId>
      <artifactId>lombok</artifactId>
      <version>${lombok.version}</version>
    </path>
  </annotationProcessorPaths>
</configuration>

如果没有使用 projectlombok，只用这个配置

<plugin>
  <artifactId>maven-compiler-plugin</artifactId>
  <version>${maven-compiler-plugin.version}</version>
  <configuration>
    <source>${maven.compiler.source}</source>
    <target>${maven.compiler.target}</target>
    <compilerArguments>
      <bootclasspath>${java.home}/lib/rt.jar</bootclasspath>
    </compilerArguments>
    <encoding>${project.build.sourceEncoding}</encoding>
  </configuration>
</plugin>
