With the tagline being, “write once, run anywhere”, it’s no wonder that Java has grown in popularity among good programmers who prefer to spend their time relaxing in cafes rather than sitting and writing tediously repetitive lines of code. This error can frequently occur when you try to run the program: java.lang.IllegalArgumentException: Malformed \uxxxx encoding. This is a popular error made by many coders. So, why did the error occur, and how could it be resolved? We’ll talk about everything with you.
Why Does The Error: java.lang.IllegalArgumentException: Malformed \uxxxx encoding Occur?
You are trying to run mvn install in your project today, and you are getting the following error.
java.lang.IllegalArgumentException: Malformed \uxxxx encoding. at java.util.Properties.loadConvert (Properties.java:672) at java.util.Properties.load0 (Properties.java:455) at java.util.Properties.load (Properties.java:408) at org.eclipse.aether.internal.impl.TrackingFileManager.read (TrackingFileManager.java:56)
Some Fundamental Methods For ”java.lang.IllegalArgumentException: Malformed uxxxx encoding” issue
And, you know what, you might be able to solve that with some simple ways. We can better understand these solutions by using the cases below.
Method 1: Set JAVA_HOME
First, run mvn —version to see if this is the problem.
If the java version is incorrect, set JAVA HOME by running export JAVA HOME=$(/usr/libexec/java home) and then run mvn —version. Maven should direct you to the correct Java version.
When you run mvn install again, Maven will use the version set in your JAVA HOME.
Method 2: Remove all artifacts
In your case, you can remove all artifacts from the /.m2 directory, and re-running
mvn build solves the problem. This time, the construction was successful.
Method 3: Delete corrupted files
Besides two above mentioned solutions, there is another method to resolve ”java.lang.IllegalArgumentException: Malformed uxxxx encoding” problem. It is excluding the files which are corrupted. Let’s follow this process to do that.
Firstly, you have to run the following command to find the files which are including
\u0000 in your
grep -rnw ~/.m2 -e '\u0000'
Then you will receive the damaged files, which you must remove before you build the maven. It is a very simple solution, right? But its efficiency is very enormous. It will help you get your desired result: the error will be completely disappear and your project will run well.
Method 4: Follow these steps
Let’s follow the below steps to resolve ”java.lang.IllegalArgumentException: Malformed uxxxx encoding” error.
1. First, you have to examine the project’s properties, YML, pom.xml, logback, and other configurations to see if there are any path issues.
2. Then, let’s redownload the jar package and update the Maven repository.
3. Finally, you have to remove the resolver-status.properties file or library’s directory.
You should start the editor again in both cases. To remove the cache and restart the concept, you simply need to click the invalidate caches/restart button.
We believe that the above solutions will be beneficial to all readers.
In short, from a developing project in 1990 known only to a small group at Sun Microsystems, Java became a technology so ubiquitous that it created the digital ecosystem it is today. The solutions mentioned above have been the most effective for individuals who are still perplexed by this error: Java.lang.IllegalArgumentException: Malformed \uxxxx encoding.
