Dear friends, 

In this post, I want to share how to fix the error about Gradle installation using brew. In my case when I  try to install Gradle, I have the following errors:

In the picture above, the suggestion was executing the commands related to git. Because as of Oct 2020 Homebrew no longer creates shallow clones and updates them. However, when I try to execute them, I had the following error:

The problem described is because for some reason the Xcode tools are missing. To continue to fix the problem about Gradle installation, you must do the following:

1. First, execute the xcode-select --install command. The pictures below show the installation process.

 

 

2.- Once time, these tools had finished. The next step is to execute the commands:

git -C "/usr/local/Homebrew/Library/Taps/homebrew/homebrew-core" fetch --unshallow

git -C /usr/local/Homebrew/Library/Taps/homebrew/homebrew-cask fetch --unshallow

 

3.- Later, you must start the Gradle installation, to do this you must execute the brew install gradle command.

 

4.- Finally, execute the gradle -v command, to verify the installation.

Dear Friends,

In this post, I show how to fix the error related to Groovy in JasperStudio 6.13. Let me start.
I have a JEE project that has some reports that were designed using Ireport 5.0 with JasperReport 5.3. The problem was in updating the libraries and tools versions. Specifically to JasperReport 6.17 and JasperStudio 6.13, when I loaded the reports and try to compile them, I was the following error:

To fix it, we need to do this following:

 Change the Language

1.- Open the report in JasperStudio, place it in the Design mode and select the report in the outline view.

 

2. -  Select right-click and select the Show Properties view, in this view, you must change the language value from Groovy to Java and save it.

3. -  Finally,  compile the report.

Hello friends, when you have these errors related to JAXBException and you are using java version 9,10 o greater.

You can download the libraries (jars) o use Java 8. Because the JAXB API classes only are available in Java 6/7/8 but no in future Java versions. Since Java 9 they are part of the JEE API.

If you use Linux, you should make sure you use the correct version of the java. For this, you must select the version with command alternatives --config java

Later to select the version, you can use the java -version command, to verify the java version.
