What is the reason for the refusal: "jarsigner: attempt to rename {file} to {file} .org failed" when signing banners with ant?

I get an error message:

[signjar] jarsigner: attempt to rename C: \ workspace \ line_editor \ Lib \ icon.jar to C: \ workspace \ line_editor \ Lib \ icon.jar.orig

when trying to self-sign a set of jars with ant inside Eclipse. The ant construct did a great job with this project and similar code in other projects. I made some small changes to the code and tried to rebuild and keep getting this error.

Here is the related ant target:

<target name="sign" depends="jar" description="Signs Jars"> <genkey keystore="myKeystore1" alias="something" storepass="somethingpass" dname="CN=Classification, OU=NAPA, O=GPC, C=US"/> <signjar keystore="myKeystore1" alias="something" storepass="somethingpass"> <fileset file="${web.dir}/${jar.name}" /> <fileset dir="${lib.dir}"> <include name="*.jar"/> </fileset> </signjar> </target>

I deleted the project and pulled it out of our repository. Thus, it has the same default settings as other projects that this part does not fail. I looked at the .jar in the question and it was not only readable. I changed the name, and the following alphabetical .jar file also failed. There is no program in this folder that accesses .jars.

Any suggestions that cause?

One possibility is that the jar, which is in the lib directory, is on the class path that is used at build time. Is ${lib.dir} in the class path used in the assembly file?

You can create a separate directory for storing signed cans and specify this in the "signjar" task using the destdir attribute.

I had the same problem. Try renaming the jar file yourself. If it cannot be renamed, you can determine which application has a lock file on it. Most likely some kind of java instance. Close all Java applications and try again. (Use the task manager to make sure your java / javaw is not running.) After that, it should work.

He searches for jarsigner.exe in the JRE home directory selected for the project. If the JRE is just a JRE (not a JDK), this program will not be present.

Try installing the JRE for a specific project and make sure that it is actually a JDK.
