When I attempt to open Eclipse, I receive the alert {Failed to find a Main Class in"/Users/ericsong/Downloads/Eclipse.app/Contents/MacOS//../Eclipse/plugins/org.eclipse.equinox.launcher_1.5.700.v20200207-2156.jar".}. I'm currently running on a 10.15.4 macOS Catalina and just installed the JavaForOSX.dmg recommended by Apple, a Java SE 6 runtime. How may I resolve this issue?

Eclipse needs Java 8 or higher. And I believe on Mac you just install a JDK not just a JRE.

Thank you for getting back to me. I have already download and installed jdk-13.0.2 and jdk-8u251 for 64 bits. By editing the -vm on eclipse.ini to /usr/bin I am now able to open Eclipse, though when any class is run, I receive the error in console "Error: missing `server' JVM at `/Library/Java/JavaVirtualMachines/jdk-13.jdk/Contents/Home/lib/server/libjvm.dylib'.
Please install or use the JRE or JDK that contains these missing components." How may I resolve this issue?
