New fernflower fork project
by Jess Sightler
I have created a new project within Windup for maintaining a fork of
Fernflower with Java 7 compatibility and a Maven pom. Maybe we can start
releasing and keeping this up to date separately from windup core?
It is here:
https://github.com/windup/windup-fernflower
I think we can switch Windup to use this as part of 2.6.0, if noone
objects to that.

Deployment / run exceptions analysis use case // Fwd: Re: Java_opts, memory, cannot reset buffer???
by Ondrej Zizka
On the F2F meeting, I suggested to include the deployment / run
exceptions analysis amongst long term goals for Windup.
This is a use case.

Enum and Enum constants as a javaclass condition
by Marek Novotny
Windup team,
I am looking for a help/advice how to create Javaclass condition for
usages of Enums and more specifically Enum constants.
It seems that current features supported in
org.jboss.windup.ast.java.data.TypeReferenceLocation is not enough to
recognize Enums outside import declaration.
Am I something overlooking or it is not just implemented - created
https://issues.jboss.org/browse/WINDUP-1002 for the follow up.

Re: [windup-dev] Fwd: [WindUp] Regular expression to detect filesystem paths
by Ondrej Zizka
Hi Roman,
1) Yes, the rule seems useful, thanks! You can create a PR, or shall I?
2) How about leaving out the <where>:
<filecontent filename="{*}.jsp" pattern="import=""" />
<where> is generally useful if you need to match a regex, or refer to
the value somewhere else in the rule.

Cool, I read your yesterday email and suggested " instead of " and

Fwd: [WindUp] Regular expression to detect filesystem paths
by Marek Novotny
adding windup-dev ml as this could be interested to Windup community.
Romain,
I would go with simplified pattern for every unique occurrence to more
more general one.
So try to use <or></or> and condition patterns in it.
Something like the following:
<rule id="filesystem-paths-properties">
<when>
<or>
<filecontent filename="{*}.{extensions}"
pattern="{filesystem}" />
<filecontent filename="{*}.{extensions}"
pattern="{netfilesystem}" />
<filecontent filename="{*}.{extensions}"
pattern="page import="{filesystem}" />
</or>
</when>
<perform>
<hint message="File system properties" effort="1"
severity="mandatory">
<message>
TODO
</message>
</hint>
</perform>
<where param="extensions">
<matches pattern="(java|properties|jsp|jpsf|tag|xml|txt)" />
</where>
<where param="filesystem">
<matches pattern="(\S:[\\|/])" />
</where>
<where param="netfilesystem">
<matches pattern="(\\\\ntfileserver\)" />
</where>
<where param="netfilesystem">
<matches pattern="" />
</where>
</rule>

Hi,
I am very obfuscated to create a rule to identify some filesystem paths
patterns. I am trying to detect when the code (.java, .properties) have
the following entries:
* "c:\\"
* "e:\\"
* "c:/"
* "e:/"
* "\\\\ntfileserver\"
* "page import="""
My first approach is similar to:
<rule id="filesystem-paths-properties">
<when>
<filecontent filename="{*}.{extensions}"
pattern="{filesystem}" />
</when>
<perform>
<hint message="File system properties" effort="1"
severity="mandatory">
<message>
TODO
</message>
</hint>
</perform>
<where param="extensions">
<matches pattern="(java|properties|jsp|jpsf|tag|xml|txt)" />
</where>
<where param="filesystem">
<matches pattern="((c|e):|[\\])" />
</where>
</rule>
However I am detecting cases as "Message: " as a pattern. How could I
create a rule to identify these cases?
Thank you very much in advance
PD: What is the better mail list to send it?

Deps in windup-rules-java-api
by Ondrej Zizka
Hi,
I've noticed that in the pom.xml of $subj, there is:
<dependency>
<groupId>org.jboss.windup.ast</groupId>
<artifactId>windup-java-ast</artifactId>
<classifier>forge-addon</classifier>
<scope>compile</scope>
</dependency>
<dependency>
<groupId>org.jboss.windup.rules.apps</groupId>
<artifactId>windup-rules-base</artifactId>
<classifier>forge-addon</classifier>
<scope>compile</scope>
</dependency>
Shouldn't that be of scope provided, and listed in ../addon/pom.xml ?
