使用Eclipse WTP忽略Gradle传递项目依赖项

[英]Ignore gradle transitive project dependencies using eclipse WTP

 原文  2013-09-10 13:40:08  4   1    java/ eclipse/ build/ gradle/ eclipse-wtp

问题描述

I have a war project (project A) that has a compile dependency on another project that contains shared libraries (project B), however I don't want the transitive dependencies of the project B to be included on the WTP deployment. 我有一个战争项目（项目A），该项目对包含共享库的另一个项目（项目B）具有编译依赖性，但是我不希望项目B的传递性依赖性包含在WTP部署中。

When I generate the war file using gradle the transitive dependencies from Project B are ignored as I want to, however WTP keeps copying all libs into the /WEB-INF/lib directory and therefore I have classloader issues. 当我使用gradle生成war文件时，我想忽略Project B的传递依赖关系，但是WTP会将所有库都复制到/ WEB-INF / lib目录中，因此存在类加载器问题。

I have tried to to ignore transitive dependencies from Project B using transitive = false and ignoring specific dependencies with exclude both at dependency and configuration level with not success so far and I can't find what I'm doing wrong. 我试图使用transitive = false忽略Project B的可传递依赖关系，并忽略了在依赖关系和配置级别上同时exclude特定依赖关系，但到目前为止还没有成功，我找不到我做错了什么。

Thanks in advance. 提前致谢。

After a massive search through net and digging into so many Gradle and WTP stuff, I was able to get this working. 在通过网络进行大量搜索并挖掘了这么多Gradle和WTP内容之后，我得以使它工作。 Basically, there are three ways to ignore dependencies in WTP deploy directory (or I am aware of only three of them!). 基本上，有三种方法可以忽略WTP部署目录中的依赖性（或者我只知道其中三种！）。

1. Setting transitive to false 1.将传递条件设置为false
As you have mentioned in the question and the syntax is like: 正如您在问题中提到的，语法类似于： 

compile('group.id:jar.name:1.0') {transitive = false}
runtime('group.id:jar.name:1.0') {transitive = false}

This should prevent the dependant JARs of being added to final WTP directory. 这应防止将依赖的JAR添加到最终WTP目录中。

2. Excluding using provided syntax 2.不包括使用提供的语法
Gadle comes with a feature to prevent dependencies of being added to final WAR file which in here can be used to prevent them of being copied to WTP deploy dir. Gadle带有一项功能，可以防止将依赖项添加到最终的WAR文件中，在此处可以使用该功能来防止将依赖项复制到WTP部署目录中。 And here is the syntax: 这是语法： 

providedCompile 'group.id:jar.name:1.0'
providedRuntime 'group.id:jar.name:1.0'

3. HACK!! 3.哈克！
Here comes the most interesting part. 这是最有趣的部分。 What if none of the above works? 如果以上都不起作用怎么办？ I found this thread on STS jira which is about same issue and that pointed me to this solution which did not work for me but gave me a clue to do my own hack as follow. 我在STS jira上发现了这个线程， 该线程是关于同一问题的，这使我指出了该解决方案， 该解决方案对我不起作用，但为我提供了以下做我自己的方法的线索。 In the build script I added following code to ignore the dependencies manually: 在构建脚本中，我添加了以下代码来手动忽略依赖项： 

subprojects { 
    project.afterEvaluate {
        eclipse.classpath.file.withXml {
            it.asNode().'classpathentry'.each { entry ->
                def path = entry.@path.toLowerCase()
                if (path.contains('your-jar-to-ignore')) {
                    entry.attributes.each { attr ->
                        if (attr.attribute.@name.contains('org.eclipse.jst.component.dependency')) {
                            entry.remove(attr)
                        }
                    }
                }
            }
        }
    }
}

It hacks into the process of generating .classpath file (which is done by gradle) and prevents it of adding dependency attribute to the specified JAR. 它侵入了生成.classpath文件的过程（由gradle完成），并阻止其将依赖项属性添加到指定的JAR中。 This way it doesn't get copied to WTP deploy directory. 这样，它不会被复制到WTP部署目录。
Hope this helps people who land on this page, but I really think either Eclipse or Gradle people should fix this issue as it is very frustrating. 希望这对登陆此页面的人有所帮助，但是我真的认为Eclipse或Gradle的人都应该解决此问题，因为它非常令人沮丧。
