# VisualVM (2.2) sources repository

VisualVM is a visual tool integrating commandline JDK tools and lightweight profiling capabilities. See https://visualvm.github.io for details, downloads and documentation.

## Get the tools

Use Apache Ant 1.9.15 or above and Oracle JDK 8 to build VisualVM from this repository.

## Get the sources

First download or clone this repository into directory `visualvm`. There are two project suites included:
  * visualvm (`visualvm/visualvm`) - suite for the core VisualVM tool
  * plugins (`visualvm/plugins`) - suite for the VisualVM plugins available in Plugins Center

## Configure the dependencies

Then download and extract the [NetBeans Platform 22](https://github.com/oracle/visualvm/releases/download/2.2/nb220_platform_20250323.zip) into directory `visualvm/visualvm` (should create `visualvm/visualvm/netbeans`).

## How to build

To build VisualVM, use `ant build-zip` command in the `visualvm/visualvm` directory. 

## How to run

To run VisualVM, use `ant run` command in the `visualvm/visualvm` directory.

## Build and run plugins

To build or run the plugins suite, use `ant build` or `ant run` in the `visualvm/plugins` directory. This will automatically build the zip distribution of the core VisualVM tool into `visualvm/visualvm/dist/visualvm.zip` and extract it into the `visualvm/plugins/visualvm` directory. After that the build of the plugins suite continues to build each of the individual plugins. Running the plugins suite means starting VisualVM with all the plugins installed.

Generate the Maven artifacts
 
 First prepare the binaries:
 
   1. Build VisualVM tool as described above
   2. Expand/decompress the generated `visualvm.zip` file in `visualvm/dist`.
   3. Generate the NBMs by running: `ant nbms`. This will generate a folder `build/updates` containing all the NBMs.
 
 To generate the artifacts use [`org.apache.netbeans.utilities:nb-repository-plugin`](https://bits.netbeans.org/mavenutilities/nb-repository-plugin/index.html). Make sure the current directory is still `visualvm/visualvm`.
 
 To install the artifacts into your local repository use the following command:
 
 ```
 mvn \
 -DnetbeansInstallDirectory=dist/visualvm   \
 -DnetbeansNbmDirectory=build/updates   \
 -DgroupIdPrefix=org.graalvm.visualvm  \
 -DforcedVersion=RELEASE22   \
 org.apache.netbeans.utilities:nb-repository-plugin:populate
 ```
 
 To publish the artifacts into a remote repository use the following command:
 
 ```
 mvn
 -DnetbeansInstallDirectory=dist/visualvm   \
 -DnetbeansNbmDirectory=build/updates   \
 -DgroupIdPrefix=org.graalvm.visualvm  \
 -DforcedVersion=RELEASE22   \
 -DdeployUrl=<URL to the remote repo> \
 -DdeployId=<repository id referenced in your settings.xml>   \
 -DskipInstall=true  \
 org.apache.netbeans.utilities:nb-repository-plugin:populate
 ```
