如何从Gradle中调用7zip来取消标记Jar [英] How Do I Call 7zip From Gradle To Unsign A Jar

问题描述

我想批量使用gradle取消签名一些罐子，但我不想使用蚂蚁因为它太慢了。

使用7zip命令行要快得多：

  7z.exe d activemq-pool-5.7.0.jar META-INF / SIGFILE。* 
  

其中SIGFILE是之前签名的名称。

我试图在gradle中这样做

  printlnUnsigning jars
 file（unsignedFolder +/jars\").listFiles().each {File file  - > 
 exec {
 workingDir'../tools'
 commandLine'7z.exe'，'d'，file.absolutePath，'META-INF / SIGFILE。*'
} 
} 
  

但是，我收到错误消息：

 启动进程'命令'7z.exe''。工作目录：D：\ code\project\tools命令：7z.exe d D：\ code\project\build\unsigned\jars\activemq-pool-5.7.0.jar META- INF / SIGFILE。* 
：signWebstart FAILED 
：signWebWebstart（Thread [Daemon，5，main]）已完成。花了0.109秒。 
 
失败：构建失败，出现异常。 
 
 *出错：
任务'：unsignJars'的执行失败。 
> 7z.exe''
  

解决方案

感谢这篇文章，我意识到它应该是什么。

我正在使用7zip的命令行版本 - 7za。在 http://p7zip.sourceforge.net/ 上也有一个unix版本，所以我将它们都包装在一起使用我的脚本并使用以下内容：

  import org.apache.tools.ant.taskdefs.condition。 Os 
 
任务unSignJars（）{
 if（Os.isFamily（Os.FAMILY_WINDOWS））{
 println*** WINDOWS
 exec {
可执行文件7za.exe
 argsd，temp.jar，META-INF / SIGN.RSA
} 
} else if（Os.isFamily（Os。 FAMILY_UNIX））{
 println*** UNIX
 exec {
可执行文件7za
 argsd，temp.jar，META-INF / SIGN .RSA

}其他{
 println***不支持
} 
} 
  

这种方法比使用Java nio快两倍 http：// t hinktibits.blogspot.ca/2013/02/Delete-Files-From-ZIP-Archive-Java-Example.html ，它本身的速度是OP中提及的ant方法的两倍。

  import java.util。*; 
 import java.net.URI; 
 import java.nio.file.Path; 
 import java.nio.file。*; 
 import java.nio.file.StandardCopyOption; 
 public class ZPFSDelete {
 public static void main（String [] args）throws Exception {
 
 / *在HashMap中定义ZIP文件系统实例* / 
 Map<字符串，字符串> zip_properties = new HashMap<>（）; 
 / *我们想读取一个现有的ZIP文件，所以我们将其设置为False * / 
 zip_properties.put（create，false）; 
 
指定要作为文件系统读取的ZIP文件的路径* / 
 URI zip_disk = URI.create（jar：file：/my_zip_file.zip） ; 
 $ b $ *创建ZIP文件系统* / 
尝试（FileSystem zipfs = FileSystems.newFileSystem（zip_disk，zip_properties））{
 / *获取ZIP文件中的路径以删除ZIP条目* / 
路径pathInZipfile = zipfs.getPath（source.sql）; 
 System.out.println（关于从ZIP文件中删除条目+ pathInZipfile.toUri（））; 
 / *执行删除* / 
 Files.delete（pathInZipfile）; 
 System.out.println（File successfully deleted）; 
} 
} 
} 
  

但是，unix zip -d再次快两倍，但不便携。

I want to batch Unsign some jars with in gradle but I don't want to use the ant jar method as it is too slow.

Using the 7zip command line is much faster:

7z.exe d activemq-pool-5.7.0.jar META-INF/SIGFILE.*

Where SIGFILE is the name of the previous signature.

I am trying to do it in gradle like this

    println "Unsigning jars"
    file(unsignedFolder + "/jars").listFiles().each { File file ->
        exec {
            workingDir '../tools'
            commandLine '7z.exe', 'd', file.absolutePath, 'META-INF/SIGFILE.*'              
        }
    }   

However, I get the error:

Starting process 'command '7z.exe''. Working directory: D:\code\project\tools Command: 7z.exe d D:\code\project\build\unsigned\jars\activemq-pool-5.7.0.jar META-INF/SIGFILE.*
:signWebstart FAILED
:signWebstart (Thread[Daemon,5,main]) completed. Took 0.109 secs.

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':unsignJars'.
> A problem occurred starting process 'command '7z.exe''

解决方案

Thanks to this post I realised what it should be.

I am using the command line version of 7zip now - 7za. There is also a unix version at http://p7zip.sourceforge.net/ so I am packaging them both with my script and using something along the lines of the following:

import org.apache.tools.ant.taskdefs.condition.Os

task unSignJars() {
  if(Os.isFamily(Os.FAMILY_WINDOWS)) {
    println "*** WINDOWS "
    exec {
        executable "7za.exe"
        args "d", "temp.jar", "META-INF/SIGN.RSA"
    }
  } else if(Os.isFamily(Os.FAMILY_UNIX)) {
    println "*** UNIX "
    exec {
        executable "7za"
        args "d", "temp.jar", "META-INF/SIGN.RSA"
    }
  } else {
    println "*** NOT SUPPORTED "
  }
}

This method is twice as fast as using Java nio http://thinktibits.blogspot.ca/2013/02/Delete-Files-From-ZIP-Archive-Java-Example.html which in itself is twice as fast as the ant method mention in the OP.

import java.util.*;
import java.net.URI;
import java.nio.file.Path;
import java.nio.file.*;
import java.nio.file.StandardCopyOption;
public class ZPFSDelete {
    public static void main(String [] args) throws Exception {

        /* Define ZIP File System Properies in HashMap */    
        Map<String, String> zip_properties = new HashMap<>(); 
        /* We want to read an existing ZIP File, so we set this to False */
        zip_properties.put("create", "false"); 

        /* Specify the path to the ZIP File that you want to read as a File System */
        URI zip_disk = URI.create("jar:file:/my_zip_file.zip");

        /* Create ZIP file System */
        try (FileSystem zipfs = FileSystems.newFileSystem(zip_disk, zip_properties)) {
            /* Get the Path inside ZIP File to delete the ZIP Entry */
            Path pathInZipfile = zipfs.getPath("source.sql");
            System.out.println("About to delete an entry from ZIP File" + pathInZipfile.toUri() ); 
            /* Execute Delete */
            Files.delete(pathInZipfile);
            System.out.println("File successfully deleted");   
        } 
    }
}

However, unix zip -d is twice as fast again but it isn't portable.
