Error CS2044: /sourcelink switch is only supported when emitting PDB, error CS2045: /embed switch is only supported when emitting a PDB., Java SDK default drop to version 1.8.0

[denisyakimov07]

Description

After release 20231115.2.0 my Android build started falling.
The reason: the Java SDK for default became Java SDK version 1.8.0

Image version: '20231115.2.0'

Image version: '20231029.1.0'

The first problem I am working around is setting up Java SDK version manually.

After fix, we started to see other problems during the production Android build.

CSC : error CS2044: /sourcelink switch is only supported when emitting PDB. [D:\a\1\s\************************.csproj]
CSC : error CS2045: /embed switch is only supported when emitting a PDB. [D:\a\1\s\*************************.csproj]

There are no changes in the source code between builds.
Some default settings are missing in the new image.

Hey, we will take a look

[denisyakimov07]

I was able to fix the Error CS2044 and error CS2045.

After research, we can see the difference in 2 runs.

image version: '20231115.2.0'

image version: '20231029.1.0'

In my case, one of the dependent projects had no release configuration, debug only. Another project was fixed when i add

    <DebugType>None</DebugType>
    <DebugSymbols>false</DebugSymbols>

I can confirm this broke all of our Xamarin Android builds with the following error:

15:14:14 [DBG] C:\Program Files\Microsoft Visual Studio\2022\Enterprise\MSBuild\Xamarin\Android\Xamarin.Android.Legacy.targets(254,5): error XA0031: Java SDK 11.0 or above is required when using $(TargetFrameworkVersion) v13.0. [D:\a\1\s\src\**redacted**.csproj::TargetFramework=MonoAndroid13.0]

We don't use the task. We use raw MSBuild. Here's an internal link:

Hello! The xamarin components of VS 17.8 started to require JDK 11 it seems, the default JDK version on the windows-2022 image is 8 so that's why you started seeing this error. You should not rely on the JDK version image set as default and did right with JavaToolInstaller@0 usage (alternatively the actions/setup-java should be used if one is using GitHub Actions rather than Azure DevOps). It looks like nothing actable for us left here, so I am going to close the issue, feel free to reach us out again if some other questions left.

I've confirmed that running the JavaToolInstaller task before building our Xamarin projects fixed our issues on both Linux and Windows.
