i download geogebra source code from https://github.com/geogebra...

but i got building errors as shown on the picture. I tried both OpenJDK8 and OpenJDK11.

I see "Problem 14: After accidental removal of Parser.java, Eclipse does not regenerate it from the .jj sources" from https://dev.geogebra.org/tr... , but i don't understand very well. such as what does .jj source means?

there is a class Parser defined in tools.jar in JDK, but it is an abstract class. So, i wonder where is this missing Parser class defined?

d3ab0e4543421205eb43ce3f057555e1 fixed by installing sf.eclipse.javacc-1.5.33-updatesite.zip

still have issue described in https://help.geogebra.org/t...

i may need to upgrade JavaCC

install sf.eclipse.javacc-1.5.33-updatesite.zip cause subsequent error https://help.geogebra.org/topic/stringprovider-cannot-be-resolved-to-a-typeparser-java

see resolution in link above. in short, i should have just use gradlew to build the project before import into eclipse
