[Scons-users] Javac scan '.java' file less some '.class' file

[钟文冰]

Javac scan '.java' file less some '.class' file
* Version of SCons  ------------------------------- 3.0.5
* Version of Python ------------------------------- 3.7.0
* Version of JDK ----------------------------------- 1.8.0_144
* Which python distribution if applicable -------- python.org
* How you installed SCons --------  python setup.py install
* What Platform are you on? ---------------------- Windows 7
* How to reproduce your issue?  Please include a small self contained reproducer. Likely a SConstruct should do for most issues.
1 .  less Generic class 

--------------------------------SConstruct---
print([str(cls) for cls in Java('.','.')])
--------------------------------Example_demo.java--
package bag;
import bag.MyInterface;
import java.util.*;

public class Example_demo{
    public static void pppp() {
        MyInterface<List<String>> obj = null;
        obj = new MyInterface<List<String>>() {
            @Override
            public String getName() {
                return "MyInterface";
            }
            public String value() {
                return "ABC";
            }
        };
    }
}
--------------------------------MyInterface.java--
package bag;
interface MyInterface<T> {
    public String getName();
}

* How you invoke scons (The command line you're using "scons --flags some_arguments")
scons

scons ouput -------------------->
['bag\\Example_demo.class', 'bag\\MyInterface.class']

This generates three class files:
['bag\\Example_demo$1.class', 'bag\\Example_demo.class', 'bag\\MyInterface.class']
but scons does not know about the first one, so it is not included in the jar.
----------------------------------------------------------------------------------
I suggest modifying the file scons\SCons\Tool\JavaCommon.py
Line 63  “ _reToken = re.compile(r'(\n|\\\\|//|\\[\'"]|[\'"\{\}\;\.\(\)]|' +
                          r'\d*\.\d*|[A-Za-z_][\w\$\.]*|<[A-Za-z_]\w+>|' +
                          r'/\*|\*/|\[\])')”
to          “ _reToken = re.compile(r'(\n|\\\\|//|\\[\'"]|[\'"\{\}\;\.\(\)]|' +
                          r'\d*\.\d*|[A-Za-z_][\w\$\.]*|<[A-Za-z_][\w<>]+>|' +
                          r'/\*|\*/|\[\])')”

2 .  less Generic class 

--------------------------------SConstruct---
print([str(cls) for cls in Java('.','.')])
--------------------------------FinalCls.java--
public final class FinalCls {
    private static class InnerSubClass extends Object {
        public String toString() {
            return "InnerSubClass of FinalCls";
        }
    }
    public static final Object STATIC_FINAL_OBJ = new InnerSubClass();
}

* How you invoke scons (The command line you're using "scons --flags some_arguments")
scons

scons ouput -------------------->
['FinalCls$InnerSubClass.class', 'FinalCls.class']

This generates three class files:
['FinalCls$1.class', 'FinalCls$InnerSubClass.class', 'FinalCls.class']
but scons does not know about the first one, so it is not included in the jar.
-----------------------------------------------------------------------------------
Lost files(FinalCls$1.class) do not seem to affect the execution of the program
