Kotlin 胶囊 Gradle 错误

Question

我在尝试使用 Gradle 创建胶囊时遇到错误。

Failed to find Premain-Class manifest attribute in 

E:\Dropbox\Projects\Kotlin\Games\CSGO\Charlatano\build\libs\capsule.jar
Error occurred during initialization of VM
agent library failed to init: instrument
CAPSULE: Client connection failed.
CAPSULE EXCEPTION: Accept timed out while processing null null: null (for stack trace, run with -Dcapsule.log=verbose)
Press any key to continue . . .

这是我的 build.script

buildscript {
    ext.kotlin_version = '1.1-M01'
    ext.jna_version = '4.3.0-SNAPSHOT'
    ext.quasar_version = '0.7.6'
    ext.gdxVersion = '1.9.4'

    repositories {

        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"

}

task capsule(type: Jar, dependsOn: jar) {
    archiveName = "capsule.jar"
    from jar // embed our application jar
    from { configurations.runtime } // embed dependencies

    from(configurations.capsule.collect { zipTree(it) }) { include 'Capsule.class' } // we just need the single Capsule class

    manifest {
        attributes(
                'Main-Class'  :    'Capsule',
                'Application-Class'   : mainClassName,
                'Extract-Capsule' : 'false', // no need to extract the capsule
                'Min-Java-Version' : '1.8.0',
                'JVM-Args' : run.jvmArgs.join(' '),
                'System-Properties' : run.systemProperties.collect { k,v -> "$k=$v" }.join(' '),
                'Java-Agents' : configurations.quasar.iterator().next().getName()
        )
    }
}

run {
    jvmArgs "-javaagent:${configurations.quasar.iterator().next()}"
}

这是它生成的 jar 文件。 https://dl.dropboxusercontent.com/u/91292881/ShareX/2016/09/libs.zip

请告诉我哪里不对，谢谢！

Answer 1

capsule 中的 MANIFEST.md 似乎损坏了，缺少如下 Premain-Class 属性：

Premain-Class: org.eclipse.package.ObjectSizeFetcher

您的 capsule 清单文件应如下所示：

Manifest-Version: 1.0
Created-By: 1.5.0_18 (Sun Microsystems Inc.)
Premain-Class: org.eclipse.package.ObjectSizeFetcher

检查类似问题以查找更多信息："Failed to load Premain-Class manifest attribute" while trying to get the size of an object using java agent
