0 Preface
This article mainly explains the installation of Jprofiler under mac m1, and the installation core steps are also applicable to other systems
1. Installation
If you are using eclipse, you can install MAT directly in the plug-in, because I am using idea development, so I choose to install the MAT tool independently
1. Download address: https://www.eclipse.org/mat/downloads.php
Choose the version you need, here I choose the mac arm architecture version, note that the latest version 1.14 needs jdk17+
if it is jdk1.8, you need to download other versions: https://www.eclipse.org/mat/previousReleases.php
Here I choose version 1.7.0. I tried versions 1.8.0 and 1.8.1 before, but the page cannot be displayed after installation, so choose carefully
2. If it is a mac, it may appear 无法打开“mat”，因为它来自身份不明的开发者. For other systems, please skip this step
Enter 系统偏好设置- 隐私与安全性, choose to still open
Select Open
3. If the following error occurs during the installation process
java.lang.IllegalStateException: The platform metadata area could not be written
Enter /mat.app/Contents/MacOSthe folder and execute the command:
./MemoryAnalyzer -data ./dump
4. If it continues to appear
The JVM shared library "/Library/Java/JavaVirtualMachines/zulu-8.jdk/Contents/Home/bin/../jre/lib/server/libjvm.dylib"
does not contain the JNI_CreateJavaVM symbol.
This is because the jdk that is adapted to the arm version—zulu jdk is used. We switch jdk to x86 architecture
vim ~/.bash_profile
Effective environment variable
source /etc/profile ~/.bash_profile
Check the effect
5, execute again./MemoryAnalyzer -data ./dump
When the dump folder is found, close the command window
6. Re-open MAT, the following interface appears, indicating that the installation is successful
7. Here you will find that the interface does not move, refer to the official instructions: https://www.eclipse.org/forums/index.php/t/1090889/
8. Download the component from the first step in the above figure, and then execute the command replacement:
mv 下载包路径/swt-4.7.1a-cocoa-macosx-x86_64/swt.jar 你的MAT路径/mat.app/Contents/Eclipse/plugins/org.eclipse.swt.cocoa.macosx.x86_64_3.104.2.v20160212-1350.jar
# eg
mv /Users/wuhanxue/Downloads/swt-4.7.1a-cocoa-macosx-x86_64/swt.jar /Library/software/MAT_1.7.0/mat.app/Contents/Eclipse/plugins/org.eclipse.swt.cocoa.macosx.x86_64_3.104.2.v20160212-1350.jar
9. Open MAT again and find that it is running normally. Open a new dump file for analysis, and it is also running normally. The installation is successful!
