尝试创建jar时清单文件中的行太长

Question

在尝试构建jar时,我遇到了太长的行错误.清单文件中的长行是Class-Path行,因为应用程序使用了许多第三方库.不用说,我正在使用Windows :-(和Eclipse Java 1.6

我想Class-Path: lib还是Class-Path: lib/,但他们没有工作.

Answer 1

由于其中包含jar文件的数量,类路径太长.«没有行可能长于72个字节(不是字符),采用UTF8编码形式.»[来自docs:java 5,java 8 ; «线长»部分].

使用以下方法解决问题:

(1)使用单独的行,避免一行为java包名列表

(2)在每个后续行之前键入前一个空格,例如:

Class-Path:
 ...jar
 ...jar
 ...jar

Answer 2

单个字符对我不起作用(Java 8,IntelliJ).我在开始时使用了两个字符,并且在行的末尾没有字符(从上面的例子中看不出来)和最后两个新行,例如

Manifest-Version: 1.0
Main-Class: com.mypackage.MyApp
Implementation-Version: 2.0.0
Class-Path:  newLibs/asjava.zip
  newLibs/activation.jar
  newLibs/axis-ant.jar
  newLibs/axis.jar
  newLibs/bcel-5.1.jar
  newLibs/commons-discovery-0.2.jar
  newLibs/commons-logging-1.0.4.jar
  newLibs/datanucleus-api-jdo-4.2.0-release.jar
  newLibs/datanucleus-api-jpa-4.1.4.jar
  newLibs/datanucleus-cache-4.0.4.jar
  newLibs/datanucleus-core-4.1.5.jar
  newLibs/datanucleus-geospatial-4.1.0-release.jar
  newLibs/datanucleus-guava-4.1.3.jar
  newLibs/datanucleus-java8-4.2.0-release.jar
  newLibs/datanucleus-jdo-query-4.2.0-release.jar
  newLibs/datanucleus-jodatime-4.1.1.jar
  newLibs/datanucleus-jpa-query-4.0.4.jar
  newLibs/datanucleus-rdbms-4.1.6.jar
  newLibs/dom4j-1.6.1.jar
  newLibs/ehcache-1.1.jar
  newLibs/ehcache-core-2.2.0.jar
  newLibs/geronimo-jta_1.1_spec-1.1.jar
  newLibs/guava-15.0.jar
  newLibs/h2-1.3.168.jar
  newLibs/ibmjsse.jar
  newLibs/javax.jdo-3.2.0-m3.jar
  newLibs/javax.persistence-2.1.1.jar
  newLibs/jaxrpc.jar
  newLibs/jdo-api-3.1-rc1.jar
  newLibs/jdom.jar
  newLibs/joda-time-1.6.jar
  newLibs/jtds-1.2.jar
  newLibs/log4j-1.2.14.jar
  newLibs/mail.jar
  newLibs/saaj.jar
  newLibs/servlet-api.jar
  newLibs/wsdl4j-1.5.1.jar
  newLibs/xercesImpl.jar
  newLibs/xml-apis.jar

我还避免在一行上放置多个罐子,因为它似乎不起作用(即使行数少于72个字节).

让我得出这个解决方案的原因是(1)我一直得到各种类未找到的异常,当然和(2)当我在jar文件中检查生成的清单文件时,罐子之间的间距丢失了 - 我假设它默默地失败了,因为除了没有找到的类之外没有报告错误.我的工作,生成的清单文件如下所示:

Answer 3

Voodoochild的答案让我走上了正确的轨道,但对我来说并不是那么清楚所以引用规格:

No line may be longer than 72 bytes (not characters), in its UTF8-encoded form. If a value would make the initial line longer than this, it should be continued on extra lines (each starting with a single SPACE).
