如何解决库冲突(apache commons-codec) [英] How to resolve a library conflict (apache commons-codec)

问题描述

我对 Android 库有疑问.

I have a problem with Android libraries.

我想使用库 org.apache.commons.codec.binary.Hex(1.6 版)中的 Hex.encodeHexString(Byte Array) 方法

I would like use the method Hex.encodeHexString(Byte Array) from the library org.apache.commons.codec.binary.Hex (version 1.6)

在我的 Android 平台 (SDK 2.3.1) 上，commons-codec 库版本 1.3 已经存在，但该版本中尚不存在该方法(仅 encodeHex() ).

On my Android platform (SDK 2.3.1), the commons-codec library version 1.3 already exist but the method doesn't exist yet in this version (only encodeHex() ).

我将 1.6 版的 jar 库添加到我的 Eclipse 项目中(进入/libs 目录)，但是当我在模拟器上运行该项目时，我得到了这个:

I added the jar library of version 1.6 into my Eclipse project (into /libs directory) but when I run the project on Emulator, I get this :

E/AndroidRuntime(1632): FATAL EXCEPTION: main
E/AndroidRuntime(1632): java.lang.NoSuchMethodError: org.apache.commons.codec.binary.Hex.encodeHexString

如何指示操作系统好库在哪里?

How can I indicate the OS where is the good library?

我在 Mac OS X 上使用 Eclipse Juno 和 Java 1.6.0

I'm using Eclipse Juno with Java 1.6.0 on Mac OS X

抱歉我的英语不好，提前致谢！

Sorry for my bad english and thanks in advance!

我的问题显然可以用 jarjar 工具解决.http://code.google.com/p/google-http-java-client/issues/detail?id=75

EDIT : My problem could be apparently solved with jarjar tool. http://code.google.com/p/google-http-java-client/issues/detail?id=75

有人可以帮我使用这个工具吗?我不知道如何创建 Ant Manifest 或 jar 文件.

Someone could help me with this tool? I don't know how to create an Ant Manifest or a jar file.

谢谢

使用Maven Shade Plugin解决的问题

这个插件允许在编译时重命名冲突库的包名.

This plugin allows to rename package names of conflicted library at compilation.

用法:

   <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-shade-plugin</artifactId>
        <executions>
            <execution>
            <phase>package</phase>
            <goals>
                <goal>shade</goal>
                </goals>
            <configuration>
                    <relocations>
                        <relocation>
                                <pattern>org.apache.commons</pattern>
                                    <shadedPattern>com.example.shaded.org.apache.commons</shadedPattern>
                        </relocation>
                    </relocations>
                        <promoteTransitiveDependencies>true</promoteTransitiveDependencies>
            </configuration>
            </execution>
        </executions>
    </plugin>
