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

Use Apache Ant 1.9.9 or above and Oracle JDK 8 to build VisualVM from this repository.

First download or clone this repository into directoryvisualvm. 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

Then extract theNetBeans Platform 12.4 into directoryvisualvm/visualvm (should createvisualvm/visualvm/netbeans).

To build VisualVM, useant build-zip command in thevisualvm/visualvm directory. To run VisualVM, useant run command in thevisualvm/visualvm directory.

To build or run the plugins suite, useant build orant run in thevisualvm/plugins directory. This will automatically build the zip distribution of the core VisualVM tool intovisualvm/visualvm/dist/visualvm.zip and extract it into thevisualvm/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.
