VisualVM (master) 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 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.
