用于多个maven模块项目的proguard [英] proguard for multiple maven module project

问题描述

在多模块maven项目中，我有一个插件引用了proguard。

我的项目的功能已经过全面测试，可以运行......直到我添加了proguard。

我的项目结构

父-Pom

-module-a-pom

-module-b-pom

tester-pom

1. 模块-b对模块-a具有依赖性。
   
2. 模块-a和模块-b都是安装到我的本地maven仓库。
   
3. 测试人员对模块-a和模块-b都有依赖性。


4. 我的proguard.conf文件位于文件系统上的parent-pom pom.xml文件。


5. 我在module-a和module-b pom.xml文件中配置了proguard。

我的proguard配置看起来像这样：

<插件>
< groupId> com.github.wvengen< / groupId>
< artifactId> proguard-maven-plugin< / artifactId>
< version> 2.0.8< / version>
<执行次数>
<执行>
< id> process-classes-with-proguard< / id>
<阶段>程序类< /阶段>
<目标>
< goal> proguard< / goal>
< /目标>
<配置>
< injar>课程< / injar>
< proguardVersion> 5.1< / proguardVersion>
< proguardInclude> $ {project.basedir} /../ proguard.conf< / proguardInclude>
< libs>
< lib> $ {java.bootstrap.classes}< / lib>
< lib> $ {java.secure.socket.extension.classes}< / lib>
< lib> $ {java.cryptographic.extension.classes}< / lib>
< / libs>
< obfuscate> true< / obfuscate>
< / configuration>
< /执行>
< /执行次数>
<依赖关系>
< dependency>
< groupId> net.sf.proguard< / groupId>
< artifactId> proguard-base< / artifactId>
< version> 5.1< / version>
< scope>运行时< / scope>
< /依赖关系>
< /依赖关系>
< / plugin>

我的项目使用GSON从外部对一些传入的JSON进行反序列化

作为构建的一部分执行proguard会导致GSON代码抛出NullPointerExceptions

受到proguard影响的代码是：

  Gson gson = new Gson（）; 
类型collectionType = new TypeToken< ArrayList< MyType>>（）{}。getType（）; 
 ArrayList< MyType> myTypes = gson.fromJson（json，collectionType）; 
  

如果proguard在我的pom文件中被注释掉（所以它不会执行），这个代码我的项目的其余部分）就像一个魅力。

如何配置proguard来混淆我的代码但不破坏功能？这是可能的多模块项目？

是否任何人知道如何配置多模块maven项目的proguard？

注意：我已经尝试了此，它似乎对结果没有任何影响。

解决方案

我最终得到了这个工作：

1. 使用Windows Proguard应用程序并通过向导选择相对基本的设置
   
2. 导出配置


3. 关闭我的眼睛并按下开始按钮。

..它工作正常！

I have a plugin reference to proguard in a multi-module maven project.

The functionality of my project is fully tested and works...until I add proguard.

Structure of my Project

parent-pom
-module-a-pom
-module-b-pom

tester-pom

1. module-b has a dependency on module-a.
2. module-a and module-b are both installed to my local maven repository.
3. tester has dependencies on both module-a and module-b.
4. My proguard.conf file is next to the parent-pom pom.xml file on the file system.
5. I configure proguard in both module-a and module-b pom.xml files.

My proguard config looks like so:

<plugin> <groupId>com.github.wvengen</groupId> <artifactId>proguard-maven-plugin</artifactId> <version>2.0.8</version> <executions> <execution> <id>process-classes-with-proguard</id> <phase>process-classes</phase> <goals> <goal>proguard</goal> </goals> <configuration> <injar>classes</injar> <proguardVersion>5.1</proguardVersion> <proguardInclude>${project.basedir}/../proguard.conf </proguardInclude> <libs> <lib>${java.bootstrap.classes}</lib> <lib>${java.secure.socket.extension.classes}</lib> <lib>${java.cryptographic.extension.classes}</lib> </libs> <obfuscate>true</obfuscate> </configuration> </execution> </executions> <dependencies> <dependency> <groupId>net.sf.proguard</groupId> <artifactId>proguard-base</artifactId> <version>5.1</version> <scope>runtime</scope> </dependency> </dependencies> </plugin>

I have the added complexity that my project is using GSON to deserialise some incoming JSON from an external component I have no control over.

Executing proguard as part of the build causes the GSON code to throw NullPointerExceptions

The code that is effected by proguard is:

Gson gson = new Gson();
Type collectionType = new TypeToken<ArrayList<MyType>>(){}.getType();
ArrayList<MyType> myTypes = gson.fromJson(json, collectionType);

If proguard is commented out in my pom files (so it doesn't execute), this code (and the rest of my project) works like a charm.

How can I configure proguard to obsfuscate my code but not break the functionality? Is this possible with a multimodule project?

Does anyone out there know how to configure proguard for a multimodule maven project?

NB: I have already tried this and it seemed to make no difference to the outcome.

解决方案

I eventually got this working by:

1. Using the Windows Proguard application and selecting relatively basic settings through the wizard
2. Exporting the configuration
3. Closing my eyes and pressing the go button.

..and it worked!
