我需要在 Gradle 项目中创建 fat jar 并进行测试,其中 Main 方法位于 src/test 下。
我现在有
Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/commons/cli/CommandLineParser
当我运行由“gradle bootJar”创建的 fat jar 时。
我的 Gradle :
plugins {
id 'org.springframework.boot' version '2.1.7.RELEASE'
}
apply plugin: 'io.spring.dependency-management'
dependencies {
compile group: 'org.springframework', name: 'spring-context', version: '5.1.9.RELEASE'
compile group: 'org.springframework', name: 'spring-web', version: '5.1.9.RELEASE'
compile group: 'org.springframework', name: 'spring-aop', version: '5.1.9.RELEASE'
compile group: 'org.springframework', name: 'spring-aspects', version: '5.1.9.RELEASE'
compile group: 'org.springframework', name: 'spring-test', version: '5.0.5.RELEASE'
compile group: 'commons-cli', name: 'commons-cli', version: '1.4'
}
bootJar {
manifest {
attributes 'Start-Class': 'com.company.MainRunner'
}
from sourceSets.test.output.classesDirs
}
我的 spring.xml:
<?xml version="1.0" encoding="UTF-8"?>
<beans default-lazy-init="true" xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

</beans>
异常(exception):
Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/commons/cli/CommandLineParser

之前遵循的“gradle ShadowJar”代码运行良好,直到我将 AspectJ 添加到项目中
buildscript {
repositories {
jcenter()
mavenCentral()
}
dependencies {
classpath 'com.github.jengelman.gradle.plugins:shadow:4.0.3'
}
}
apply plugin: 'com.github.johnrengelman.shadow'
shadowJar {
manifest {
attributes 'Main-Class': 'com.company.MainRunner'
}
from sourceSets.test.output.classesDirs
configurations = [project.configurations.testRuntime]
}
运行“gradle ShadowJar”时出现错误
Unable to locate Spring NamespaceHandler for XML schema namespace [http://www.springframework.org/schema/aop]
我发现 ShadowJar 无法与 Spring 正常工作
如何为 Spring 项目创建 fat jar,其主类位于 src/test 下?
最佳答案
这个 Gradle ShadowJar 适合我
import com.github.jengelman.gradle.plugins.shadow.transformers.AppendingTransformer
shadowJar {
mergeServiceFiles()
transform(AppendingTransformer) { resource = 'META-INF/spring.handlers' }
transform(AppendingTransformer) { resource = 'META-INF/spring.schemas' }
manifest {
attributes 'Main-Class': 'com.company.MainRunner'
}
from sourceSets.test.output.classesDirs
configurations = [project.configurations.testRuntime]
}
