我正在尝试使用我的Java项目中的default-template来生成基于我的项目中指定的ivy依赖项的启动脚本。我面临的问题是,常春藤依赖关系被拾取并放入类路径中,但主项目jar没有包含在类路径中。(在尝试运行脚本时,它给出了一个类未找到异常)进一步调查和其他脚本比较我发现有一行作为。
export RUNTIME_CLASSPATH=""
在我生成的脚本中。这应该有我的项目jar的路径,但没有填充(例如:export RUNTIME_CLASSPATH="$(dirname $0)/../lib/myproject.jar:"
)
我们在哪里确切地指定了脚本中引用自身的项目(调用项目)? 我已经查看了所有其他文件,包括构建属性,常春藤,常春藤设置无济于事。 如果有人能帮助我找到我所缺少的东西,那就太好了。

ANT没有任何标准功能来生成特定于操作系统的启动脚本。您可以做的是生成executable jar,可以通过运行java来启动,如下所示:
java -jar demo.jar
可执行jar的关键特性是它的清单指定了主类和类路径:
Manifest-Version: 1.0
Ant-Version: Apache Ant 1.8.3
Created-By: 1.6.0_20-b20 (Sun Microsystems Inc.)
Main-Class: org.demo.App
Class-Path: lib/slf4j-api-1.6.4.jar lib/slf4j-simple-1.6.4.jar
以下ANT项目演示了常春藤如何协助创建可执行jar
|-- build.xml
|-- ivy.xml
`-- src
|-- main
| `-- java
| `-- org
| `-- demo
| `-- App.java
`-- test
`-- java
`-- org
`-- demo
`-- AppTest.java
运行构建
ant clean build
执行程序
java -jar build/dist/demo.jar
打包jar以使用位于相对“lib”子目录
中的依赖项build/dist/demo.jar
build/dist/lib/slf4j-api-1.6.4.jar
build/dist/lib/slf4j-simple-1.6.4.jar
