How to fix corrupted xls file by maven? - maven

Question

I have a method of generating report made with jett:
try {
InputStream inPath = ProdutoManagedBean.class.getResourceAsStream("/template.xls");
ExcelTransformer transformer = new ExcelTransformer();
transformer.transform(inPath, beans);
} catch (IOException e) {
e.printStackTrace();
} catch (InvalidFormatException e) {
e.printStackTrace();
}
I'm having an InvalidFormatException in transformer.transfom (...):
22:44:37,803 ERROR [stderr] (default task-28) org.apache.poi.openxml4j.exceptions.InvalidFormatException: Your InputStream was neither an OLE2 stream, nor an OOXML stream
I investigated that maven causes this data corruption, but I put the filter artifacts in the pom.xml and it still continues to come corrupted:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>${compiler-plugin.version}</version>
<configuration>
<encoding>UTF-8</encoding>
<nonFilteredFileExtensions>
<nonFilteredFileExtension>xls</nonFilteredFileExtension>
</nonFilteredFileExtensions>
</configuration>
</plugin>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-jar-plugin</artifactId>
<version>2.5</version>
<inherited>true</inherited>
<configuration>
<encoding>UTF-8</encoding>
<nonFilteredFileExtensions>
<nonFilteredFileExtension>xls</nonFilteredFileExtension>
</nonFilteredFileExtensions>
</configuration>
</plugin>
<plugin>

Answer 1

I was able to solve; I put this artifact in the pom.xml of the project that has the web infrastructure components:
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-war-plugin</artifactId>
<version>3.1.0</version>
<inherited>true</inherited>
<configuration>
<encoding>UTF-8</encoding>
<nonFilteredFileExtensions>
<nonFilteredFileExtension>xls</nonFilteredFileExtension>
</nonFilteredFileExtensions>
</plugin>
</plugins>
</build>
It was probably a problem caused by a specificity of the technical architecture of the project.
