gradle - Java 8上的Spring Boot应用程序的gradle wrapper失败，找不到Gracert 3:找不到证书

使用gradle wrapper命令创建gradlew文件时遇到问题。我的设置很简单:Ubuntu 14.04 + Java 8(openjdk版本“1.8.0_91”)+ Gradle 3.0

使用的教程:

https://spring.io/guides/gs/spring-boot/#scratch

https://docs.gradle.org/current/userguide/gradle_wrapper.html

这个问题的奇特之处在于gradle wrapper失败的原因是因为cacerts文件或目录显然丢失了-但实际上没有(请参阅下面的“检查cacerts文件/目录”)。虽然-请让我知道这是否是问题-这是一个链接，而不是实际的文件/目录。我不知道是否还有其他问题，因为缺少cacerts错误似乎是一系列错误的结尾，但是对调试它的任何帮助将不胜感激。

我的相关文件和输出在下面列出。

干杯

build.gradle:

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath("org.springframework.boot:spring-boot-gradle-plugin:1.4.0.RELEASE")
    }
}

apply plugin: 'java'
apply plugin: 'eclipse'
apply plugin: 'idea'
apply plugin: 'spring-boot'

jar {
    baseName = 'gs-spring-boot'
    version =  '0.1.0'
}

repositories {
    mavenCentral()
}

sourceCompatibility = 1.8
targetCompatibility = 1.8

dependencies {
    // tag::jetty[]
    compile("org.springframework.boot:spring-boot-starter-web") {
        exclude module: "spring-boot-starter-tomcat"
    }
    compile("org.springframework.boot:spring-boot-starter-jetty")
    // end::jetty[]
    // tag::actuator[]
    compile("org.springframework.boot:spring-boot-starter-actuator")
    // end::actuator[]
    testCompile("junit:junit")
}

问题/错误:

org.apache.http.ssl.SSLInitializationException: /usr/lib/jvm/java-8-openjdk-amd64/jre/lib/security/cacerts (No such file or directory)

检查cacerts文件/目录:

vagrant@vagrant:/vagrant/BootTutorial$ ll /usr/lib/jvm/java-8-openjdk-amd64/jre/lib/security/cacerts
lrwxrwxrwx 1 root root 27 Apr 22 13:29 /usr/lib/jvm/java-8-openjdk-amd64/jre/lib/security/cacerts -> /etc/ssl/certs/java/cacerts
vagrant@vagrant:/vagrant/BootTutorial$

运行gradle包装器的输出:

最佳答案

您可能正在遇到一个错误，该错误使您的符号链接(symbolic link)与报告的here和here悬卡在一起。建议的解决方案是重新安装ca-certificates-java软件包。像这样:

$ sudo dpkg --purge --force-depends ca-certificates-java
$ sudo apt-get install ca-certificates-java
