解决办法就是在pom.xml中指定maven-compiler-plugin的版本,该版本会同时影响LanguageLevel和JavaCompiler,修改后默认就成了这里设置的版本。 添加下面的配置: <build><plugins><plugin><groupId>org.apache.maven.plugins</groupId><artifactId>maven-compiler-plugin</artifactId><version>3.1</version><configuration>...
The choice of the compiler does not affect the source code language level, and also the bytecode target level and linking. That is, irrespective of which compiler is used, the bytecode is linked against the JDK associated with the module, and the resulting code levels are exactly the ones ...
The Java compiler is written in Java. The Java run-time system is written in ANSI C with a clean portability boundary which is essentially POSIX-compliant. There are no "implementation-dependent" notes in the Java language specification. 4.3 Robust Java is intended for developing software ...

The IDE invokes the Java programming language compiler (javac), which takes your source file and translates its text into instructions that the Java virtual machine can understand. The instructions contained within this file are known as bytecodes. Run the program The IDE invokes the Java applica...
