Question

我是新手，现在就学习。我正在尝试使用gradle构建一个可运行的jar（我的构建jar应该从命令提示符运行）。我刚开始使用一个带有依赖项的简单HelloWorld项目，并尝试使用gradle构建它。我不是在使用maven。所以我将依赖jar添加到项目文件夹中的lib文件夹中。以下是详细信息。

Gradle版本：3.1 Eclipse版本：Neon

HelloWorld.java

package com.padhu.test;
import org.joda.time.LocalTime;

public class HelloWorld {

    public static void main(String[] args) {
        // TODO Auto-generated method stub

        LocalTime currentTime = new LocalTime();
        System.out.println("The current local time is: " + currentTime);

        System.out.println("Hello World");

    }

}

项目结构：

project_structure

build_path_snap

build_path_details

build.gradle文件：

apply plugin: 'java'
apply plugin: 'application'
mainClassName = 'com.padhu.test.HelloWorld'

repositories {

   flatDir {
      dirs 'lib'
   }
}

dependencies {


    compile files(fileTree(dir: 'lib', includes: ['*.jar']))

    }

jar {
  manifest {
    attributes(

      'Main-Class': 'com.padhu.test.HelloWorld'
    )
  }
}

我可以在我的cmd中成功执行gradle build并生成jar文件。但在jar文件中，我只能看到HelloWorld文件夹结构，但无法看到依赖文件。所以我无法从命令提示符运行jar，因为我得到NoClassDefFoundError: org/joda/time/LocalTime ..

我尝试通过搜索和阅读博客来解决问题。但我无法成功运行jar。

请帮帮我。

看来，您误解了SELECT itm.Id , ISNULL(itm.Debit, 0) AS Debit , ISNULL(itm.Credit, 0) AS Credit , itm.State , itm.DocCreateDate , ISNULL(itm.Num, 0) AS Num , ISNULL(itm.DocTypeRef, 0) AS DocTypeRef , itm.Year , itm.Month , ISNULL(itm.DebitCount, 0) AS DebitCount , ISNULL(itm.CreditCount, 0) AS CreditCount , itm.DL , itm.DL2 , itm.DL3 , itm.DL4 , itm.DL5 , itm.DL6 , itm.DL7 , ISNULL(itm.FCRef, 0) AS FCRef , itm.FollowUpNum , ISNULL(itm.BranchRef, 1) AS BranchRef , itm.DocHeaderRef , ISNULL(itm.RowNum, 0) AS RowNum , ISNULL(itm.DailyNum, 0) AS DailyNum , ISNULL(itm.TempNum, 0) AS TempNum , ISNULL(itm.RefNum, 0) AS RefNum , itm.Descript , itm.Count , itm.FollowUpDate , itm.FCVal , itm.FCRateVal , itm.FactorNum , ISNULL(itm.DebitFCVal, 0) AS DebitFCVal , ISNULL(itm.CreditFCVal, 0) AS CreditFCVal , sl.Id AS SLRef , sl.SLCode , sl.Title AS SLTitle , CASE WHEN ISNULL(sl.DLSRef, 0) > 0 THEN 1 ELSE 0 END AS HasDL , CASE WHEN ISNULL(sl.DLSRef2, 0) > 0 THEN 1 ELSE 0 END AS HasDL2 , CASE WHEN ISNULL(sl.DLSRef3, 0) > 0 THEN 1 ELSE 0 END AS HasDL3 , CASE WHEN ISNULL(sl.DLSRef4, 0) > 0 THEN 1 ELSE 0 END AS HasDL4 , CASE WHEN ISNULL(sl.DLSRef5, 0) > 0 THEN 1 ELSE 0 END AS HasDL5 , CASE WHEN ISNULL(sl.DLSRef6, 0) > 0 THEN 1 ELSE 0 END AS HasDL6 , CASE WHEN ISNULL(sl.DLSRef7, 0) > 0 THEN 1 ELSE 0 END AS HasDL7 , CASE WHEN ISNULL(sl.HasFC, 0) > 0 THEN 1 ELSE 0 END AS HasFC , 1 AS HasFollow , tl.Id AS TLRef , tl.Title AS TLTitle , tl.TLCode , gl.Id AS GLRef , gl.Title AS GLTitle , gl.GLCode , gl.Balance AS GLBalance FROM Acc.DocItem AS itm LEFT OUTER JOIN Acc.SL AS sl ON itm.SLRef = sl.Id LEFT OUTER JOIN Acc.TL AS tl ON sl.TLRef = tl.Id LEFT OUTER JOIN Acc.GL AS gl ON tl.GLRef = gl.Id WHERE ( itm.SLRef > 0 )插件的行为方式。它不会创建一个所谓的fat-jar，它包含所有它的依赖项，而是创建一个jar并能够运行它，将所有依赖项添加到类路径中。

您可以按如下方式运行您的应用程序：

application

或者您可以使用自动应用的分发插件，并使用脚本创建项目分发，以启动它，并将所有依赖库分别放在单独的文件夹中。只需运行它：

gradle run
