Eclipse, java8 is built with an ant and the bootstrap class path is not set with -source8 error.

As the title suggests, I am too new to know how to set classpass.
Currently, javac is unknown in the following configuration:

jdk-14.0.2
jre1.8.0_261
tomcat 8.5.57

Below is the error.Thank you for your cooperation.

I don't know much about it, but I'll write a workaround for you when I'm into it.

 C:\Users\tono\tomcat\pleiades\workspace\apache-tomcat-8.5.57\webapps\web\WEB-INF\build-web.xml

<property name="version.target" value="12"/>
<property name="version.source" value="12"/>

Is there a description like this?

The above is an example of Java 12, but it seems that this description does not match the actual SDK version, and an error is displayed when the required library, etc., is not found.
I think we can avoid errors by matching this version.

Also, if you search for "bootstrap class path is not set with -source8" as the search word, similar cases will be quite successful.Why don't you review your settings using examples that are similar to your environment?
