我想我需要在我的Pom.xml中添加一些东西,但我不明白要添加什么!我的pom.xml:

我需要添加到我的pom.xml中?
确保在存储库的根目录中包含system.properties
文件,其中包含以下内容:
java.runtime.version=10
有关更多信息,请参阅Heroku documentation on Java versions
仅从Java9(https://maven.apache.org/plugins/maven-compiler-plugin/compile-mojo.html)开始支持-release参数。确保您的maven安装至少使用Java9。
尝试使用版本3.8.0而不是3.7.0。还要确保将JAVA_HOME设置为Java 8安装。见this link
还有另一种选择,而不是在repo位置添加属性文件。
您可以在POM.xml中添加此代码:
<properties>
<java.version>1.8.0_171</java.version>
</properties>
