我有一个使用Gradle构建的Groovy应用程序。我可以使用gradle run
正确运行它,但我想创建一个胖JAR来简化部署。我已添加说明
jar {
dependsOn configurations.runtime
from { configurations.runtime.collect { it.isDirectory() ? it : zipTree(it) } }
}
到我的build.gradle
。
似乎生成了包含大量依赖关系的JAR,但是当我尝试使用java -jar myproject.jar
运行它时,我收到了错误
Exception in thread "main" java.lang.NoSuchMethodError: org.objectweb.asm.ClassWriter.<init>(Z)V

更多细节,如果可以提供帮助
供参考,以下是完整的build.gradle
:
apply plugin: 'groovy'
project.group = 'mycompany.myproject'
archivesBaseName = 'myproject'
project.version = '0.1'
manifest.mainAttributes('Main-Class' : 'mycompany.myproject.Main')
apply plugin: 'application'
mainClassName = 'mycompany.myproject.Main'
repositories {
mavenCentral()
}
buildscript {
apply from: 'https://github.com/valkolovos/gradle_cobertura/raw/master/repo/gradle_cobertura/gradle_cobertura/1.2/coberturainit.gradle'
}
jar {
dependsOn configurations.runtime
from { configurations.runtime.collect { it.isDirectory() ? it : zipTree(it) } }
}
dependencies {
groovy group: 'commons-cli', name: 'commons-cli', version: '1.0'
groovy group: 'org.codehaus.groovy', name: 'groovy', version: '1.8.0'
compile group: 'log4j', name: 'log4j', version: '1.2.9'
compile group: 'org.codehaus.groovy.modules.http-builder', name: 'http-builder', version: '0.5.2'
compile group: 'groovy', name: 'groovy-xmlrpc', version: '0.3'
testCompile group: 'junit', name: 'junit', version: '4.0'
}
run {
if (project.hasProperty('args')) {
args project.args.split('\\s+')
}
}
cobertura {
coverageSourceDirs = sourceSets.main.java.srcDirs + sourceSets.main.groovy.srcDirs
}
错误似乎所在的Main
类的来源是
package mycompany.myproject
class Main {
static main(args) {
def env = args ? args[0] : 'prod'
new Coordinator().run(env)
}
}
答案 0 :(得分:1)
听起来包含错误的ASM版本,虽然我不确定原因。无论如何,使用groovy-all
代替groovy
通常更简单,更安全,它也应该解决这个问题。
您不应该使用Groovy 1.8.0,而是使用最新的次要版本(1.8.6)。
