Dead code detection

[Oliver Rettig <Ol...@orat.de>]

Hi all,

I need functionality in Netbeans to find dead code. Andy ideas about a plugin?

I have found

https://blogs.oracle.com/geertjan/dead-code-detection-with-netbeans-ide

but it is outdated and I can not find the source code. Maybe this plugin can help

@Geertjan have you saved this code somewhere?

In concrete we have a java library project which is a Wrapper to a c++ native lib. To create a 
platform independent jar-file we want to add the native code build for several operating 
systems into the the jar. 

We found that the

https://jogamp.org/ 

project includes great code to do this but the code is part of a big project. Not the state is 
that we have a copy a subset of the classes which seems to be needed into our project. But 
most of this code is not needed. There are too many classes/methods we have now to check 
if they are really needed. Thats why we need a tool in the Netbeans IDE to automatize this.

best regards
Oliver

Hi Neil,

thanks for the hint to LWJGL. Do you know where in the repository https://github.com/LWJGL 
the code for jative-jar building resides?

I think it makes sense to evaluate other possibilities for us. We are often in the situation 
native-jars would be great. So we think about to create a seperate open source project with 
libs and tools to do this.

best regards
Oliver

Partly OT - JogAmp might not be the best starting point. Pretty sure LWJGL Core will do this, 
and it's much more modularized so this bit might be small enough as is. JNA also has some 
code that does this IIRC.


Best wishes, 


Neil

Hi Mark,

thanks for the link but this is not the code - not even an Netbeans plugin. But it is interesting 
to have a look into the source code. The code can be used by an ant-task, so maybe it is 
usable in the netbeans IDE.

best regards
Oliver

The code appears to be here:

https://github.com/evernat/dead-code-detector

I just found it with a little searching. I have no idea what state the
code is in, how to create a plugin from it, or how it handles newer
versions of Java.

. . . just my two cents
