Class size
Hello,
I have a basic question...
If i compile a simple hello world java program using javac in ant i get a
different size as compared to class compiled with maven plugin.
My java source and target it 1.6.
What is the reason. Can anyone help me with this. I will really appreciate
your help.
Thanks

I did an example and could see that behaviour.
build.xml
---------
<project>
<mkdir dir="target/ant-classes"/>
<javac srcdir="src/main/java" destdir="target/ant-classes" includeantruntime="false" />
</project>
src/main/java/MyClass.java
--------------------------
public class MyClass {}
pom.xml

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

<modelVersion>4.0.0</modelVersion>
<groupId>de.materne.ant</groupId>
<artifactId>class-size</artifactId>
<version>1.0.0-SNAPSHOT</version>
</project>
Class-Size:
Ant : 122 Byte
Maven: 246 Byte
When adding 'debug="on"' to Ant's <javac> it produces also a 246 Byte class file.

Next idea is using different compile flags, e.g. debug.

Are you sure that Maven and Ant are using the same JDK?

There are multiple compiler settings which can influence class size.
Including debug information (source file, line, local vars - defaults
to on in Maven and off on Ant) and I guess presence of some annoation
processors.
Are you using the same java version for compiling with Ant and Maven?
(and youare sure you do not use eclipse or jikes?
https://maven.apache.org/plugins/maven-compiler-plugin/non-javac-compilers.html)
Ithink you could dump the classes with "javap -l -c -s -p -verbose" to
see potential differences. How big of a difference do you see?
