what do i need to add to my pom.xml ? 我需要添加什么到我的pom.xml中?
The -release argument is supported only since Java9 ( https://maven.apache.org/plugins/maven-compiler-plugin/compile-mojo.html ). 仅从Java9开始才支持-release参数( https://maven.apache.org/plugins/maven-compiler-plugin/compile-mojo.html )。 Make sure your maven installation is using at least Java9. 确保您的maven安装至少使用Java9。
Ensure that you have system.properties
file in the root directory of your repository with the following contents: 确保存储库的根目录中具有system.properties
文件,其中包含以下内容:
java.runtime.version=10
For more info see the Heroku documentation on Java versions 有关更多信息,请参见有关Java版本的Heroku文档。
There's another option instead of adding the properties file in the repo location. 除了在回购位置添加属性文件外,还有另一种选择。
You can add this code in POM.xml: 您可以在POM.xml中添加以下代码:
<properties>
<java.version>1.8.0_171</java.version>
</properties>
Remove <release>10</release>
from pom.xml and add system.properties
in resources with content java.runtime.version=10
. 从pom.xml中删除<release>10</release>
,并在内容为java.runtime.version=10
资源中添加system.properties
。 It should work with jdk 10. Or you can change the JDK as per your need. 它应该与jdk 10一起使用。或者,您可以根据需要更改JDK。
