Burp Import Issues

[0x42424242]

Hi,

When trying and import the standalone JAR downloaded from https://github.com/ikkisoft/ParrotNG/releases I receive the following error message;

java.lang.ClassNotFoundException: burp.BurpExtender
    at java.net.URLClassLoader$1.run(URLClassLoader.java:372)
    at java.net.URLClassLoader$1.run(URLClassLoader.java:361)

    at burp.p8e.a(Unknown Source)
    at burp.syd.run(Unknown Source)
    at java.lang.Thread.run(Thread.java:745)

In an attempt to rectify the issue I attempted to build it from the source. When trying to compile however I get the following error...

burp/BurpExtender.java:72: illegal start of type
                    List<IScanIssue> issues = new ArrayList<>(1);
                                                            ^
1 error

Any ideas? Help greatly appreciated.

Which version of Java and Burp Pro? Also, which OS?

[0x42424242]

Sorry for the lack of detail, I should have included that in the original post.

Java Version: 1.8.0_31
Burp: Burpsuite Pro v1.6.12
OS: OSX 10.10

Hi Peleus,

I tried the JAR on the exact same configuration and I was NOT able to reproduce this issue.
It looks like a problem with the classpath, but "burp.BurpExtender" is clearly in the jar and it's referenced in the MANIFEST.

Any additional information will be appreciated.

Thanks,
Luca

Same problem here using Burp 1.6.20 on OS X.
However using BApp Store it was installed without any problem.

Hi Stefano,
Which Java JRE? java -version

As a workaround, you could probably use $ java -cp ./parrotng_v0.2.jar -jar burpsuite_pro_v1.6.20.jar

Hi Luca,
sorry for the delay.

$ java -version
java version "1.8.0_25"
Java(TM) SE Runtime Environment (build 1.8.0_25-b17)
Java HotSpot(TM) 64-Bit Server VM (build 25.25-b02, mixed mode)

I haven't tried the workaround because it's working after I installed it via the BApp Store. Maybe there is something wrong with Burp. But it works, so not a problem.
