how to install the old version of joern?

[zainebmb]

in joern-parse.py file :

Does the joern path from the config file refer to its path in this repository
do i have to clone this repo: https://github.com/ives-nx/dwk_preprocess/tree/main/joern_slicer/joern to use joern-parse?
if yes, shouldn't the path in the config file be the full path: joern_slicer/joern/joern-parse ?
else how to install joern?
I need an answer please, thanks!

Thank you for your question. Here are the steps to use joern:

1. clone https://github.com/ives-nx/dwk_preprocess/tree/main/joern_slicer/joern
2. build joern to produce joern-parse
3. put the path to joern-parse in your local environment into the config file. (could be absolute path)

thank you!
another question please, does this old version support python? can i generate PDG for python code using this joern parser?

[jumormt]

Only C/C++ code I'm afraid.

[zainebmb]

when i run build.gradle file it raises this error

what can be wrong?

[jumormt]

Run build.sh to build. If you still get the error you can try an older version of Gradle (see https://joern.readthedocs.io/en/dev/installation.html).

i am using compatible versions of java ( 17) and gradle (7.3) and i installed all the necessary dependencies yet the problem persists!

[zainebmb]

i guess the cause of that error is that the task deploy can't find the task build in build.gradle file
how can i do ?

在 joern-parse.py 文件中：

配置文件中的 joern 路径是否引用其在此存储库中的路径，我是否必须克隆此存储库：https://github.com/ives-nx/dwk_preprocess/tree/main/joern_slicer/joern 使用 joern-parse？如果是，配置文件中的路径不应该是完整路径吗：joern_slicer/joern/joern-parse ？否则如何安装 Joern？我需要一个答案，谢谢！

您好 是怎么安装的这个老版本的joern ，可以教我一下么 十分感谢 求！！！！

谢谢你的提问。以下是使用 joren 的步骤：

1. 克隆 https://github.com/ives-nx/dwk_preprocess/tree/main/joern_slicer/joern
2. 构建 joern 以生成 joern-parse
3. 将本地环境中的 joern-parse 路径放入配置文件中。（可以是绝对路径）

可否展开说一下具体的joern安装配置呢 老师 求！！！
