What should I do if it prompts that java loading fails when building git?

With the rapid development of software development, Git, as a distributed version control system, has become an indispensable tool for many developers and teams. However, when building Git, you sometimes encounter some problems, such as error messages indicating that Java loading failed. This article will describe the causes and solutions to this problem.

1. Problem description

When installing and configuring Git, sometimes "Error occurred during initialization of VM, java/lang/NoClassDefFoundError: java/lang/Object" or "Error occurred" During initialization of VM, java/lang/ClassNotFoundException: java/lang/Object” and other prompts appear, which means that Java loading failed.

2. Cause of the problem

The reason for this problem is that the path of the Java SDK (Software Development Kit) is incorrectly configured in the Git path. When Git starts, it uses Java instructions to create a Java Virtual Machine (JVM). If there is no correct Java configuration path, Java will not be loaded.

3. Solution

1. Check the Java path

First, you need to ensure the correctness of the Java installation path. In Windows systems, you can check by doing the following:

1) Open the "Control Panel", click "Programs", and then click "Java".

2) In the "Java Control Panel", click the "Java" tab to view the path of the Java runtime environment.

If the Java path is incorrect, you need to modify the Java installation path in the system environment variable.

2. Modify the Git configuration file

If the Java path has been configured correctly, then you need to modify the Git configuration file and specify the correct Java path. The following is how to repair the configuration file in Windows system:

1) Enter the bin folder in the Git installation directory.

2) In the bin folder, right-click git.exe and select "Properties".

3) In the properties dialog box, click the "Compatibility" tab, pull down and select "Run this program as an administrator".

4) Open the git-core directory under the bin folder and find the file named "git-exec".

5) Right-click the "git-exec" file and click "Edit".

6) Find the following line of code:

my ($jbase) = $ENV{JAVA_HOME} =~ /^(.*)$/;

7) Change Replace it with the following line of code:

my ($jbase) = "C:/Program Files/Java/jre1.8.0_261" =~ /^(.*)$/;

Note: Replace "C:/Program Files/Java/jre1.8.0_261" with your Java installation path.

8) Save and close the "git-exec" file and restart Git.

The above method is applicable to the Git configuration file in Windows systems. The Git configuration files of other operating systems may be different from this.

4. Summary

If you encounter the problem of Java loading failure when building Git, you need to check the Java path and Git configuration file. Once you make sure it's configured correctly, you can happily use Git and enjoy the convenience it brings.
