The search found that the error was a static constant error, but no fundamental solution was found.
I tried a variety of solutions, such as modifying the port number, modifying the IP address, modifying the storage path, etc., but the methods such as replacing the jdk installation were ineffective.
After inputting the error information into Chatgpt, although the solutions provided by GPT are ineffective, I noticed its description.
According to the log information you provided, the java.lang.ExceptionInInitializerError exception occurs due to the initialization of the Guice (Google Guice) injection framework when Gitblit starts. The root cause of the exception is java.lang.reflect.InaccessibleObjectException, which indicates that some methods cannot be accessed. This may be due to the stricter accessibility rules introduced by the modular system in Java 9+.
So I guessed it was because the latest JDK rules were more stringent when installing jkd. The current JDK versions on the official website are 21 and 17. I tried to modify the installation and found that it didn’t work.
After uninstalling the JDK, I directly installed the JRE [https://www.java.com/zh-CN/], and the deployment was completed directly without any errors.
