When I try to clean my projects I am now getting two errors that stops the build process...
Could not delete: D:\myworkspace\library\bin\library.jar.
Could not delete 'D:\myworkspace\google-play-services_lib\bin\google-play-services_lib.jar'.
I am running Eclipse as administrator on my Windows 7 computer.
I have been updating all of my libraries recently in order to use Google Cloud Messaging but I have no idea if this has anything to do with it.
If I delete the jar files manually, then start eclipse and clean it will run ok. But now I need to do this anytime I want to recompile.
I have googled this error but I can't find anything on it.
Thanks,
Gary
When you get the error in Eclipse, try using Process Explorer or similar tool to try to determine what running process is holding on to that file.

My team is working on a Java application that runs on Jboss WildFly, using Maven to resolve dependencies and Primefaces.
We're using Eclipse to build, deploy and run the server. Eclipse does most of the work, building the WAR file, deploying it to server and running it.
Now we need to create an script that performs all those steps because it has to run on remote server.
.
The steps would be something like this...
1 Run Maven:
$M2_HOME/bin/mvn clean install
2 Build project to a war file
3 Deploy war file into the WildFly deployment folder
$WILDFLY_HOME/bin/jboss-cli.sh --connect --command="deploy --force [PATH_TO_WAR]"
4 Start server
$WILDFLY_HOME/bin/standalone.sh
.
I can perform every step but once the server is running it don't seem to be any changes in the application. I think this is because the WAR file has to be built optimizing it for JBoss. Eclipse has a way to do this when exporting the project. I need to know how to do that from command.
EDIT:
The real problem is that Jboss is not updating the published project when i run it from bash script. I thought it was because i had to build it on a specific way. I was wrong. The build is fine, just running Maven the deploy is done. The thing is that even if i rebuild project and redeploy it, server doesn't seem to notice at all.
I've tried deleting tmp, lib and data folders from standalone folder, and nothing happens. I also deleted standalone/deployed sub files and folders and got the same result.
The only way i achieve the result i'm expecting is getting into Eclipse, go to Servers tab, right click on JBoss Wildfly and click on 'Clean...'. This options seems to clean cache, rebuild and re publish the application in a right way that i don't know. I didn't find any answers on google.
eclipse server clean option
Give a look on Eclipse war export: optimize for a specific server runtime.
Quoting from #Konstantin Komissarchik's answer :
Eclipse itself doesn't do anything with that option. What happens is
dependent on a particular server adapter. Many of the adapters don't
do anything with this option either, but they might in the future.
If a server adapter does support export optimization, it has the
option of displaying custom options beneath that pop-up list of
runtimes, so that's a good cue to use to see if something will
actually happen.
So taking in consideration that in your provided image there is no custom options below Wildfly 9 selection, I am pretty sure that this option does not perform any optimization at your exported war so you can totally omit it in your new build-deploy process.
How can i build the war file from command, knowing it will have to run on Wildfly?
We are also deploying applications for a long time on several versions of Widlfy with the same approach as you are planning to, without the optimization thing. I can ensure you that we have not faced any performance issue.
I used to work on an IntelliJ project that was started before I started working on it. This project had a configuration that allowed me to generate an EXE file that could easily be sent to windows users.
It would generate a massive EXE file bundled with all the needed JARs of the application, and upon running it the first time, it would silently "install" itself into the AppData folder, as if it were a regular windows setup file, even though the user would not even notice it doing that installation.
I am trying to configure a project in IntelliJ to do the exact same thing, but first I have not been able to output the exe file by selecting "exe" as the Java FX native bundle type. It just generates a .jnlp and .jar file. When I select "all", as per some other post here in stackoverflow, it generates an exe file, but only with a few kb in size, which does not contain any of the .jar files that should be part of it. Moreover, when I try to open it, it just crashes saying the main class was not found.
Am I missing some setting for building the project? I am using IntelliJ 2018.3.2
Here are some screenshots:
I have been able to get past this error, after changing the verbosity of the compilation and going through the logs.
There was a log message which helped fixing this:
The process complained about the Inno Setup Compiler missing, which was right. Makes me wonder why IntelliJ would have that feature built in if it depends on external tools but does not notify the user clearly of this.
Detected [iscc.exe] version 0.0 but version 5.0 is required.
After going to the Inno Setup site, downloading and installing the tool, I was able to get the executable to be generated.
Now I am struggling with another error, which is the executable complaining about the main class referenced in the Artifact not being found, but at least I have moved past the first problem! Going to tackle this one now...
The best solution for this is using exe generator software.
There is plenty of exe generators out there.
EXE4J is the most simple & easy tool to use.
In EXE4J,
You can upload your main jar file and select the main class.
I think this will be solved your problem.
This may be due to you`ve extracted Jars to your output root, while you neet to Put it(you can check difference by deleting everything from your output root in Output Layout screen and then just right click on jar on the right side, you will see two options here, try another one
I'm developing a project with web services in JAVA, in JDEV.
I'm using Oracle Middleware and I am getting this error when trying to run every time:
Error occurred during initialization of VM
java/lang/ClassNotFoundException: error in opening JAR file C:\Oracle\Middleware\Oracle_Home\oracle_common\jdk\jre\lib\rt.jar
Process exited with exit code 1.
I've found people with the same issue, but apparently no fix so far:
https://community.oracle.com/thread/3783771?start=0&tstart=0
My workaround is to copy and paste the .jar in my local project folder.
But is pretty annoying to do this everytime I want to run.
It works after doing it, so I'm sticking to that for now.
I'm using Windows and my app does not "crash" when running in a Web Logic Server so I'm thinking is something in my laptop.
The .jar is fine, and is not 0kb.
Modify access control of the rt.jar file in windows.
Give full control to the windows logged in user.
I am getting an error when I try to build my project in NetBeans. I am using JBoss 5.1.0 server and have attached that to my project. The error is -
The following error occurred while executing this line:
.../myPath/build-impl.xml:176: The Java EE server classpath is not correctly set up - server home directory is missing.
Either open the project in the IDE and assign the server or setup the server classpath manually.
For example like this:
ant -Dj2ee.server.home=<app_server_installation_directory>
I am using Mac OS X Lion.
I was missing a library. When I right clicked the project and went to libraries, it showed me library missing. I added the library and did a clean and build and the error disappeared
Clean builds did not help me, either. I took a look at project.properties and found that j2ee.server.home was not set anywhere, although j2ee.platform.classpath depends on it.
I do have Weblogic Server set up under /home (on a Linux machine).
So, I closed the project and added a line to project.properties:
j2ee.server.home=/home/blister/wls/wlserver
(where wlserver = the server name)
And reopened the project. Presto, the app now builds. It still doesn't know where the app server is, but at least I can built my jar and can worry about deploying it later. (I tell it to build a war which deploys nicely to Weblogic.)
If you are using netBeans Ide, then right click on the project. click properties. in the properties menu select Run. in that the first text box is server. There select the server. with which u want to run the project. If the server details are not configured before. configure server details and try. it wil help you to solve the above problem.
This worked for me.
Right click on the Project -> Properties -> Run
And Change the server Setting from the current server to another sever and click OK.
Wait for any background scanning to finish.
Repeat the processes 1 to 3 again this time selecting the actual server you want to run the code on.
Then try Re-Running your application.
I also had this error. However despite adding servers in the Run section of the Properties window, repeatedly no servers showed as being available to add to the Project ( again within the Run section ). The solution to being able to see a server in this server list was to run Netbeans as an admin ( which I saw Rotunba referencing in this thread..It was then possible to add a server and the project built successfully..
I solved it like this, I added in the ANT properties field
"j2ee.server.home=http://localhost/"
tolls>options>java>Ant
this in linux netbeans
It could also be as simple as not running your IDE i.e. netbeans as an administrator on your machine. I had the same problem. Wasted some time.
I have an ant build that makes directories, calls javac and all the regular stuff. The issue I am having is that when I try to do a clean (delete all the stuff that was generated) the delete task reports that is was unable to delete some files. When I try to delete them manually it works just fine. The files are apparently not open by any other process but ant still does not manage to delete them. What can I do?
I encountered this problem once.
It was because the file i tried to delete was a part of a classpath for another task.
It depends ...
The Ant process doesn't have enough permissions to delete the files (typically because they were created by a different user, perhaps a system user). Try running your Ant script as an administrative user, using Run As.
Windows is really bad at cleaning up file locks when processes die or are killed; consequently, Windows thinks the file is locked by a process that died (or was killed). There's nothing you can do in this situation other than reboot.
Get better tools to inspect your system state. I recommend downloading the SysInternals tools and using them instead of the default Windows equivalents.
Using Ant Retry task has helped me.
I've just wrapped it around the Delete Task.
You don't say if your build is run as the currently logged on user. If not, the fact that explorer.exe or other process has the directory shown can cause it to be locked as well. But deleting it in that same explorer.exe process would succeed. Try Unlocker from http://ccollomb.free.fr/unlocker/ to see what processes have the files/directories locked.
Is there something from the Ant process that is holding the files (or directory) open? This would cause the situation where you could delete them after running ant, but not during.
I faced the same problem.
I didn't have any classpath set to or antivirus running on my machine.
However, the ANT version I was using was 32 bit and the JDK I installed was 64 bit.
I installed a 32 bit JDK and the issue was resolved.
Ant versions before 1.8.0 have a bug which leads to random errors during delete operation. Try using Ant 1.8.0 or newer.
You can see the bug details here https://issues.apache.org/bugzilla/show_bug.cgi?id=45960
In my case my ant clean was failing from Eclipse, unable to remove build files. I see this from time to time. Usually succeeds on a repeat attempt. This time no.
Tried running ant clean from command line, failed Unable to delete"unable to delete".
It must have been Eclipse holding on to the problem file, when I exited Eclipse, cmd line was able to delete OK.
I've been having this problem a lot lately and it's random. One time it works, the next time it doesn't work. I'm using NetBeans (in case that matters) and I've added a lot of extra tasks to build.xml. I was having this problem in the -post-jar task. It would happen when I call unjar on the file, then delete. I suspect that NB is trying to scan the jar and this causes the lock on it.
What worked for me is to immediately rename the jar at the start of -post-jar and add a .tmp extension to it. Then I call unjar on the temp file. When I'm done I rename back to the desired jar name.
I too had the same problem and was tried of manually deleting the build directories. Finally I solved it by renaming the .jar artifact of my project to a different name from project name itself. For ex: my project was portal and my ant built script use to generate portal.jar, where eclipse ant was not able to delete this portal.jar. When i changed my build.xml to generate my .jar as portalnew.jar, eclipse was able to delete this portalnew.jar next time. Hope this helps.
You need to delete it manually in Windows. It worked for me. (Usually the files to be deleted are older versions of jar.. For example: if there exists httpcore.4.2.5.ja5r and httpcore.4.3.jar, it will try to delete 4.2.5.jar)
i faced this issue as the file the ant was trying to delete was being used by some other service/process.
I stopped the service, and then the ant build script did run through.
In my case, I stopped running Java process from Task Manager and re-run the Ant build file. The file was able to delete and build was successful.
I am seeing problems like this way too often since I switched to Microsoft Windows 10. Renaming the file immediately before removing it solved it for me:
<rename src="file.name" dest="file.name.old"/>
<delete file="file.name.old" />
For me, I am using mac so I tried sudo before ant cmd, sudo ant clean all and it did work perfectly fine.
As i've read javac will not have access to delete JAR files so you can either sudo it or find alternative.
