I am not sure about this. I wonder if Gradle is able to pull from Maven Central. Do you have more information about your setup? I will try to recreate using a container.

Please also update your Java install, I think it is below the required version for Ghidra and Protobuf. This might be the issue.

thanks, cyberkaida, my java infos as below： test@vm:~$ java --version openjdk 17.0.8 2023-07-18 OpenJDK Runtime Environment (build 17.0.8+7-Ubuntu-122.04) OpenJDK 64-Bit Server VM (build 17.0.8+7-Ubuntu-122.04, mixed mode, sharing) maybe the gradle is not able to pull from Maven Central. After make protocol, I want to do 'gradle -PGHIDRA_INSTALL_DIR="/opt/ghidra"', these is my step. The details are:

• Exception is: org.gradle.api.plugins.UnknownPluginException: Plugin [id: 'com.google.protobuf', version: '0.9.4'] was not found in any of the following sources:

• Gradle Core Plugins (plugin is not in 'org.gradle' namespace)

• Plugin Repositories (could not resolve plugin artifact 'com.google.protobuf:com.google.protobuf.gradle.plugin:0.9.4') Searched in the following repositories: .... and the gradle configure is below:

// build.gradle allprojects { repositories { // mirror maven { url 'https://maven.aliyun.com/repository/google' } maven { url 'https://maven.aliyun.com/repository/public/' } // mavenCentral() } }
