执行jar命令排除文件

Question

I followed The Java Archive Tool but couldn't find how to exclude folders.

For example, I have the files under working copy directory:

workingcopy
--src
  --.svn
  -- com
--.svn
--WebContent

I would like to compile and create jar only from the classes under src excluding all folders starting with .svn directory. I want to run it from cmd like jar -cf test.jar etc..

How can I do it?

Answer 1

This can be done with a command:

jar cf test.jar `find . -not -path "*/.svn/*" -not -type d`

The problem with jar is that if directory is passed it will be added recursively with all content. So our goal is to pass only files and only those of them which doesn't have '.svn' substring in the path. For this purpose find command is used with 2 conditions:

1. -not -path "*/.svn*" filters out all svn files
2. -not -type d filters out all directories

This will exclude empty directories from the jar though.

Answer 2

This could be a practical workaround for your problem: it will not exclude the subversion directory (directories) but include only class files (assuming, you don't put class files under version control):

jar -cf test.jar *.class

Further enhancement: separate code from class files. You don't want to check in class files (build artefacts) anyway:

workingcopy
--src
  --.svn
  -- com  // only *.java files in here and below
--.svn
--WebContent
--bin
  --com   // only *.class files in here and below

Answer 3

这可以通过构建工具（如maven 、 ant和gradle ）轻松实现（以及许多其他事情）

Answer 4

There is a concept called Export in SVN. if you use that you will get the structure without the .svn repository. It is slightly different from the Check-Out.

After this you must be able to do a regular jar command from that directory instead of the repository folder.

Answer 5

As said by javamonkey79 , I don' tthink you can do this just with the jar tool itself. What you should do is considering ant , and its jar task .

Answer 6

From Java 11 you can use exlamation mark (!) to exclude files or folders, seperated by pipe (|) Examples:

jar cvf MyJarFile.jar !(file1)


jar cvf MyJarFile.jar !(file1|folder1)

On Java 8 jar, see the great answer using find from @silnijlos

You can also use maven, ant or gradle if you have that available, reference for maven:

Answer 7

It doesn't look like the jar program by itself will be able to do this. You will need to add in some other type of script to accomplish what you are looking for.

It looks like you may be using windows, so my guess is that you could write in this missing pieces that way.

Hope this helps.
