我有一个Java项目,其中嵌入了Jetty服务器和Jersey库以提供REST服务。我使用Intellij来运行该项目,它能正常运行。
问题在于当我尝试执行生成的jar文件时。
因此,我在build.gradle文件中编写了一个用于生成jar文件的任务。以下是build.gradle中的任务:
task fatJar(type: Jar) {
baseName = project.name + '-all'
from { configurations.compile.collect { it.isDirectory() ? it : zipTree(it) } }
with jar
manifest {
attributes 'Implementation-Title': 'Gradle Quickstart', 'Implementation-Version': 1.0
attributes 'Main-Class': 'EmbeddedJetty.EmbeddedJettyMain'
}
}
当我运行以下命令时,会生成jar文件。
gradle clean build fatJar
当我尝试使用命令运行生成的jar文件时,遇到了以下错误:
java -jar projectname.rar
Error: A JNI error has occurred, please check your installation and try again

能否有人提供反馈,说明可能出了什么问题?
