如何在不使用 maven 的情况下创建 jar 时排除某些 Jar 依赖项? [英] How to Exclude Certain Jar Dependencies while creating jar without using maven?
问题描述
我正在开发一个核心 Java 项目.我正在编写一个 Apache Storm 拓扑,需要在将拓扑绑定到 jar 时排除风暴 jar.有没有办法在不使用 maven 的情况下做到这一点?我知道在 maven 中我们可以使用
但我需要一个替代方案.
I am working on a core Java project. I am writing an Apache Storm topology and need to exclude storm jars while binding the topology into jar. Is there any way to do this without using maven? I know with maven we can use <scope>provided</scope>
but I need an alternative to this.
PS:我正在使用 Eclipse.

推荐答案
如果你使用 Maven 而不是 Gradle,并且你来这里是为了在构建中排除 Storm 的 lib,我有解决方案和一个工作示例.
If you are using Maven instead of Gradle, and you come here for excluding lib of Storm in building, I have the solution and a working example.
Storm 文档 告诉我们排除 Storm 依赖并提供 指向 Maven 页面的链接,其中解释了如何执行此操作,但缺少完整示例.事实证明,我们必须创建另一个XML文件作为程序集配置的描述符,而不是直接把配置放在pom.xml
中,即使Eclipse没有抱怨把这两个文件放在一起.
The documentation of Storm tells us to exclude the Storm dependency and provides a link to a page of Maven, which explains how to do it but it lacks a full example. It turns out that we have to create another XML file as the descriptor of assembly configuration, instead of putting the configuration directly in the pom.xml
, even when Eclipse does not complain about putting the two files together.
方法如下:
我们的 pom.xml
带有 assembly
插件,指向另一个描述符 xml 文件:
We have our pom.xml
with assembly
plugins, pointing to another descriptor xml file:
<plugin>
<artifactId>maven-assembly-plugin</artifactId>
<executions>
<execution>
<id>make-assembly</id> <!-- this is used for inheritance merges -->
<phase>package</phase> <!-- bind to the packaging phase -->
<goals>
<goal>single</goal>
</goals>
</execution>
</executions>
<configuration>
<descriptors>
<descriptor>/src/main/resources/exclude-storm.xml</descriptor>
</descriptors>
<archive>
<manifest>
<mainClass>path.to.main.class</mainClass>
</manifest>
</archive>
<descriptorRefs>
<descriptorRef>jar-with-dependencies</descriptorRef>
</descriptorRefs>
</configuration>
</plugin>
注意以下部分:(应该是完整路径)
Note the part of: (should be complete path)
<descriptors>
<descriptor>/src/main/resources/exclude-storm.xml</descriptor>
</descriptors>
在这个路径中:
<?xml version="1.0" encoding="UTF-8"?>
<assembly xmlns="http://maven.apache.org/ASSEMBLY/2.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/ASSEMBLY/2.0.0 http://maven.apache.org/xsd/assembly-2.0.0.xsd">
<id>exclude-storm</id>
<formats>
<format>jar</format>
</formats>
<includeBaseDirectory>false</includeBaseDirectory>
<dependencySets>
<dependencySet>
<outputDirectory>/</outputDirectory>
<useProjectArtifact>false</useProjectArtifact>
<unpack>true</unpack>
<scope>compile</scope> <!-- note here!!!! -->
<excludes>
<exclude>org.apache.storm:storm-core:jar:1.1.1</exclude>
</excludes>
</dependencySet>
</dependencySets>
<fileSets>
<fileSet>
<outputDirectory>/</outputDirectory>
<directory>${project.build.outputDirectory}</directory>
</fileSet>
</fileSets>
</assembly>
这里我们添加Maven doc页面的设置.
Here we add the settings of Maven doc page.
最重要的是:排除格式:应该是:(参考)
The most important thing: format of exclusion: should be: (ref)
groupId:artifactId:type[:classifier]:version
还有范围!runtime
是默认的,我把它改成 compile
就可以了.
And the scope! runtime
is default, I changed it to compile
and it works.
最后编译时使用:
clean assembly:assembly
并打开调试输出以在控制台中查看完整输出.如果您:
And turn on debug output to see full output in console. If you:
- 构建成功
- 搜索输出并没有找到类似的内容:
[警告]以下模式从未在此工件包含过滤器中触发:o 'org.apache.storm:storm-core:jar:1.1.1'.
- jar 不包含
default.yaml
然后你就知道你成功了.
Then you know you have succeeded.
