Target bytecode always drop back to 1.5 in IntelliJ

Question

I have a collection of "Samples" projects. The toplevel project is empty, while it contains a lot of modules.

Unfortunately, I am often required to set target bytecode to 1.5.

I did that many times from the beginning of the project, but it still drops back to 1.5.

How to stuck with 1.8 forever?

Answer 1

You can use this in your pom:

( https://maven.apache.org/plugins/maven-compiler-plugin/examples/set-compiler-source-and-target.html )

  <plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-compiler-plugin</artifactId>
    <version>3.6.1</version>
    <configuration>
      <source>1.8</source>
      <target>1.8</target>
    </configuration>
  </plugin>

我的情况（RHEL 7，IntelliJ 2019.3.1）的问题是缺少环境变量JAVA_HOME 。
