After spending a lot of time, this is how I fixed it. I still don't know why but when the code is modified as follows, it works fine. I got the idea after seeing this solution for a similar but slightly different issue.
e: this has been fixed through Spring Boot 2.6.5 (see https://github.com/spring-projects/spring-boot/issues/30243)
Since upgrading to Spring Boot 2.6.X (in my case: 2.6.1), I have multiple projects that now have failing unit-tests on Windows that cannot start
EmbeddedKafka, that do run with Linux
There is multiple errors, but this is the first one thrown...

Known bug on the Apache Kafka side. Nothing to do from Spring perspective. See more info here: https://github.com/spring-projects/spring-kafka/discussions/2027. And here: https://issues.apache.org/jira/browse/KAFKA-13391
You need to wait until Apache Kafka
3.0.1 or don't use embedded Kafka and just rely on the Testcontainers, for example, or fully external Apache Kafka broker.
I have added
android:exported="true" to my only activity in manifest but still getting below error after updating compile sdk and target sdk version to 31.I also tried rebuilding the project , invalidating cache and restart but that didn't helped
Apps targeting Android 12 and higher are required to specify an explicit value for android:exported when the corresponding component has an intent filter defined. See https://developer.android.com/guide/topics/manifest/activity-element#exported for details.
ANSWERAnswered 2021-Oct-05 at 10:38
After the build has failed go to
AndroidManifest.xml and in the bottom click merged manifest see which activities which have intent-filter but don't have
exported=true attribute. Or you can just get the activities which are giving error.
Add these activities to your App manifest with
android:exported="true" and app
tools:node="merge" this will add exported attribute to the activities giving error.
I'm trying to use packages that require
Rcpp in R on my M1 Mac, which I was never able to get up and running after purchasing this computer. I updated it to Monterey in the hope that this would fix some installation issues but it hasn't. I tried running the
Rcpp check from this page but I get the following error:

Currently (2022-02-05), CRAN builds R binaries for Apple silicon using Apple
clang (from Command Line Tools for Xcode 12.4) and an experimental build of
If you obtain R from CRAN (i.e., here), then you need to replicate CRAN's compiler setup on your system before building R packages that contain C/C++/Fortran code from their sources (and before using
Rcpp, etc.). This requirement ensures that your package builds are compatible with R itself.
A further complication is the fact that Apple
clang doesn't support OpenMP, so you need to do even more work to compile programs that make use of multithreading. You could circumvent the issue by building R itself and all R packages from sources with LLVM
clang, which does support OpenMP, but this approach is onerous and "for experts only". There is another approach that has been tested by a few people, including Simon Urbanek, the maintainer of R for macOS. It is experimental and also "for experts only", but seems to work on my machine and is simpler than trying to build R yourself.
Warning: These instructions come with no warranty and could break at any time. They assume some level of familiarity with C/C++/Fortran program compilation, Makefile syntax, and Unix shells. As usual,
sudo at your own risk.
I will try to address compilers and OpenMP support at the same time. I am going to assume that you are starting from nothing. Feel free to skip steps you've already taken, though you might find a fresh start helpful.
I've tested these instructions on a machine running Big Sur, and at least one person has tested them on a machine running Monterey. I would be glad to hear from others.
Download an R binary from CRAN here and install. Be sure to select the binary built for Apple silicon.
I am getting an error when trying to save a model with data augmentation layers with Tensorflow version 2.7.0.
Here is the code of data augmentation:...
ANSWERAnswered 2022-Feb-04 at 17:25
This seems to be a bug in Tensorflow 2.7 when using
model.save combined with the parameter
save_format="tf", which is set by default. The layers
RandomContrast are causing the problems, since they are not serializable. Interestingly, the
Rescaling layer can be saved without any problems. A workaround would be to simply save your model with the older Keras H5 format
I am using MongoDB(Mongo Atlas) in my Django app. All was working fine till yesterday. But today, when I ran the server, it is showing me the following error on console...
ANSWERAnswered 2021-Oct-03 at 05:57
This is because of a root CA Let’s Encrypt uses (and Mongo Atals uses Let's Encrypt) has expired on 2020-09-30 - namely the "IdentTrust DST Root CA X3" one.
The fix is to manually install in the Windows certificate store the "ISRG Root X1" and "ISRG Root X2" root certificates, and the "Let’s Encrypt R3" intermediate one - link to their official site - https://letsencrypt.org/certificates/

After updating my npm packages, some of the imports from the 'vue' module started showing errors:
TS2305: Module '"../../node_modules/vue/dist/vue"' has no exported member 'X'
where X is nextTick, onMounted, ref, watch etc. When serving the project, Vue says it's "failed to compile". WebStorm actually recognizes the exports, suggests them and shows types, but the error is shown regardless. Some exports like computed and defineComponent work just fine.
What I've tried:
- Rollback to the previously used Vue version "3.2.2" > "3.0.11". It makes the abovementioned type errors disappear, but the app stops working entirely, showing lots of
TypeError: Object(...) is not a functionerrors in console and not rendering the app at all. In the terminal, some new warnings are introduced:
"export 'X' (imported as '_X') was not found in 'vue'where X is createElementBlock, createElementVNode, normalizeClass and normalizeStyle.
- Rollback other dependencies. None of the ones that I tried helped fix the problem, unfortunately.
- Manually declare the entirety of 'vue' module. We can declare the 'vue' module exports in shims-vue.d.ts, and it actually makes the errors disappear, however, this seems like a terrible, time-consuming workaround, so I would opt out for a better solution if possible.

ANSWERAnswered 2021-Aug-15 at 13:53
That named exports from composition API are unavailable means that
vue is Vue 2 at some place which has only default export. Since Vue 3 is in
dependencies and both lock file and
node_modules were refreshed, this means that Vue 2 is nested dependency of some direct dependency.
The problem needs to be investigated in lock file. It shows that
@email@example.com depends on
vue-jest@3 which depends on
A possible solution is to upgrade
@vue/cli-plugin-unit-jest to the latest version,
next. The same likely applies to other
@vue/cli-* packages because they have matching versions.

There is a bug report available for the broken git svn command, see https://github.com/git-for-windows/git/issues/3392 and https://github.com/git-for-windows/git/issues/3403.
Try the latest git for windows snapshot, look here https://wingit.blob.core.windows.net/files/index.html).

You can use Utils like any standard Java library. Please include the the jar files in your classpath. You can also use any IDE and you can run and debug the Utils component as you would do with any other Java program. Best practice is to use a build tool that supports dependency management such as Maven or Gradle. For Maven installation, please refer maven.apache.org. For Gradle installation, please refer gradle.org .
