NodeInstaller fails at renameTo Node Binary with existing NodeJS version (Windows)

What is the current behavior?
The NodeInstaller.java fails to update an existing NodeJS version (Node.exe) using the renameTo function. The task fails. If I delete the node folder manually before running the task, the NodeJS executable is installed properly.

If the current behavior is a bug, please provide the steps to reproduce.

What is the expected behavior?
Either one of:

• renameTo works as expected
• or: Try to delete any existing executable file in advance, before copying over a new version instead of using renameTo

Please mention your frontend-maven-plugin and operating system version.

Can confirm this happens on 1.6 too.

1.1, 1.2 and 1.3 gave me a nullpointerexception like this:

Failed to execute goal com.github.eirslett:frontend-maven-plugin:1.3:install-node-and-npm (install node and npm) on project PROJECT: Execution install node and npm of goal com.github.eirslett:frontend-maven-plugin:1.3:install-node-and-npm failed. NullPointerException

1.4, 1.6 and 1.6 gave me the was not allowed to rename

Is this related to #147 ?

This happens to me, too.

I encountered this Bug as well. For us the build was running on a windows Jenkins CI server with Maven 3.x and Plugin 1.6, and I think Windows 10 Enterprise x64..

The issue appears to be because of the existing workspace containing the previous node version with the folder name as ..blah..\node. So the new version that is downloaded cannot be renamed to this existing folder.
Workaround - For Jenkins - Specify (check) the Delete workspace before Build option for 1 build cycle, so that the workspace is deleted and the plugin downloads the Node version and renames it without any issue since no existing node folder is present. After build success, don't forget to un-check this option for faster builds. Locally - simply delete the node folder.

I am giving some steps to reproduce the same, in case this wasn't clear from earlier posts:
How to reproduce the same

• Assuming you have a pom.xml with the install-node-and-npm and nodeVersion tag set to say v8.11.1 like:

<build>
      <plugins>
          <plugin>
              <groupId>com.github.eirslett</groupId>
              <artifactId>frontend-maven-plugin</artifactId>
              <executions>
                  <execution>
                      <id>install node and npm</id>
                      <goals>
                          <goal>install-node-and-npm</goal>
                      </goals>
                      <configuration>
                          <nodeVersion>v8.11.1</nodeVersion>                          
                          <workingDirectory>${basedir}</workingDirectory>
                      </configuration>
                  </execution>
              </executions>
          </plugin>
      </plugins>
   </build>

• Delete the node folder in the project folder if present.
• Run a mvn clean install this will download the node version to the folder called node and do other stuff as specified in your pom.xml
• Change the nodeVersion to say v8.9.1 in the pom.xml
• Do a mvn clean install again, you should get this same error

Error:

[ERROR]

TL;DR - use Node 8.9.4

can reproduce this issue - have tried via the Windows cmd.exe and git bash console windows, both using a normal user window and one created via "run as administrator". Same error condition(s) using the following versions of NodeJs.

• 10.3.0 - error
• 8.11.2 - error
• 8.11.1 - error
• 8.10.0 - error
• 8.9.4 - success

any news on this? This should be easy to fix and is very annoying

[AlexanderEerenberg]

Same here =(

[eirslett]

I don't have access to a Windows box. If anybody fixes it and creates a PR, I can merge and release it.

[vacolane]

this bug happened to me when node was already installed on the project but I've updraged the node version on the pom.xml. To fix it I've deleted the "node" folder and restart "maven install".

[erikyuzwa]

@vacolane - this didn't work for me.

I believe I tracked down the specific code around the issue - NodeInstaller.java around L221

    this.logger.info("Copying node binary from {} to {}", nodeBinary, destination);
                if (!nodeBinary.renameTo(destination)) {
                    throw new InstallationException("Could not install Node: Was not allowed to rename "
                        + nodeBinary + " to " + destination);
                }

Figuring out how to build + test this locally, but there must be a workaround to using renameTo in this way.

[DiabolusExMachina]

@eirslett this should be very easy to fix. Just delete the file before you rename it.

Just add this line to delte the node exe before you copy it.

Files.deleteIfExists(file.toPath());  //path to existing node exe

Any notices about this ? No body did a PR to fix this ?
