How to solve : Unable to Process Jar entry

Question

I am getting this error on console. Can anyone please help me out (I am working on a Spring MVC project with GWT and maven)

SEVERE: Unable to process

Answer 1

First open the file icu4j-2.6.1.jar with any zip vievwer (7Zip for example). Check if it contains the com/ibm/icu/impl/data/LocaleElements_zh__PINYIN.class file.

Answer 2

this is work for me:

<dependency>
  <groupId>com.ibm.icu</groupId>
  <artifactId>icu4j</artifactId>
  <version>4.6</version>
</dependency>

Answer 3

I guess LocaleElements_zh__PINYIN.class file is missing in jar try replacing the jar.

Answer 4

com.ibm.icu.impl.data.LocaleElements_zh__PINYIN is a ill-formed class file inside the 2.6.1 icu4j jar file. Override or use the newer icu4j jar files, 55.0+.

Answer 5

I get this error when icu4j-xxx.jar is included in my class path. Why don't you try to remove it from your WEB-INF/lib?

Answer 6

So, in our case it didn't come from a direct dependency but rather from an indirect injection of the com.google.code.findbugs library.

You will know where it comes from by running mvn dependency:tree for your project (supposing you're using maven)

Solution for us was to use a newer version of the findbugs library (3.0.0) which appeared to be much leaner in terms of dependency content.
