Build the Aspnetcore repo

Usually the assembly goes well.

I build by .\eng\build.cmd -all -pack -arch x64 though if to check build.ps1 appears that x64 is the default option. More often I use build.cmd instances that are located in “\src”. I add comments or tests for myself so I do it regularly.

You can always to clear \artifacts and will try to build again. The order of compilation to artifacts due to the implementation of ArcadeSdk (https://github.com/dotnet/arcade/blob/main/Documentation/ArcadeSdk.md)

Recently I received a error.

D:\src\aspnetcore\eng\targets\Java.Common.targets(54,5): error MSB3073:   
The command "../gradlew  compileJava" exited with code 1.  
[D:\src\aspnetcore\src\SignalR\clients\java\signalr\core\signalr.client.java.core.javaproj]  

After careful viewing of \docs\BuildFromSource.md I noticed .\eng\scripts\InstallJdk.ps1.
After executing InstallJdk.ps1, D:\src\aspnetcore\src\SignalR\build.cmd worked successfuly.

I decided to check global.json version by git log -p global.json > temp.txt

It turned out that the jdk version has not been updated, it is the same since 2019 year. Valid version is “jdk”: “11.0.3”. So the reason is not a change in the version used during assembly. Looked further.

The script checks if “D:\src\aspnetcore.tools\jdk\win-x64\bin\javac.exe” exists. If file does not exist, so script will download “https://netcorenativeassets.blob.core.windows.net/resource-packages/external/windows/java/jdk-${JdkVersion}_windows-x64_bin.zip” “$tempDir/jdk.zip” and unzip the archive to D:\src\aspnetcore.tools\jdk\win-x64\bin

\.tools is included in .gitignore. I didn’t understand why I was getting this error because I didn’t seem to delete the \.tools content.

When the build failed, I got a message.

PS D:\src\aspnetcore\src\SignalR> .\build.cmd
Detected JDK in C:\Program Files\Java\jdk-21 (via JAVA_HOME)

This’s correct.

PS D:\src\aspnetcore> echo $env:JAVA_HOME
C:\Program Files\Java\jdk-21

From the script logic it is clear that the message is a sign that the .\tools jdk is not installed but despite this the build process will continue with a version from program files.

I have updated Java a couple of months ago. So it means that previous version was compatible with 11.0.3, v21.0.1 is not.

Now in a compile time I get a message that suits me better.

Detected JDK in D:\src\aspnetcore\eng\..\.tools\jdk\win-x64\ (via local repo convention)`
