Open JDK download

1. Preamble

• According to the company's internal cognition of JDK, Oracle JDK 8 can use the version jdk1.8.0_192, and the higher version of JDK will involve business issues, and Open JDK needs to be used
• I need to use it in my work recently JDK 17.0.4 or higher, so I need to download Open JDK 17
• This article will take Open JDK 17 as an example to introduce the download method of Open JDK

2. Download Open JDK from Open JDK official website

• After a lot of hard work on the official website of Open JDK, I finally found the download address of 17.0.5:
  • JDK Update Releases $\to$ OpenJDK 17 Updates
  • Open JDK 17 Older releases $\to$ 17.0.5 binaries (provided by adoptium)
• Among the 228 files, I found the installation package corresponding to Linux 64-bit:OpenJDK17U-jdk_x64_linux_hotspot_17.0.5_8.tar.gz
• Another official website download address introduced by some blogs , the latest version of JDK 17 is 17.0.2, which cannot meet the demand

3. Other domestic download mirrors

• The download speed is not very fast. I thought that when Win10 installed JDK 8 before , it was mentioned that using the domestic download mirror can speed up the download.
• The following is a download mirror or website that I think is OK:
  • Huawei's Open JDK download mirror , JDK17 only up to 17.0.2
  • Tsinghua's Open JDK download mirror , but its JDK17 mirror only provides the latest version: OpenJDK17U-jdk_x64_linux_hotspot_17.0.7_7.tar.gz
  • Red Hat Open JDK , the version is perfect

4. Different sources about Open JDK

• The author found that: Open JDK official website and Tsinghua University download mirror, the installation package has the hotspot logo,
  maintained by Eclipse Adoptium
• Red Hat maintains it by itself, and the naming of the installation package is also different from the former.
• If there is no problem with the content introduced in the blog "5 Things You Should Know Before Downloading and Installing OpenJDK" , it means that after JDK is open source, different manufacturers have provided compiled versions of Open JDK
• Out of belief in HotSpot, Eclipse, Tsinghua University, etc., the author finally chose the hotspotJDK installation package with the logo released by Eclipse Adoptium
