diamond operator is not supported in -source 1.5和source release 8 requires target release 1.8的问题

Error:(43, 20) java: diamond operator is not supported in -source 1.5
(use -source 7 or higher to enable diamond operator)

或者

Error:java: javacTask: source release 8 requires target release 1.8

总共要检查6个地方,

Project Structure->Project(设置图中2处Project SDK与Project language level)

Project Structure->Modules(设置图中1处Language Level)

下面2处bytecode都要设置成8

如果上面的还不行，那么需要在pom.xml中检查:

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