giving error 'Could not initialize class' in native image #95
Comments

Can you provide some example poi code on how you get this error? Keeping it as simple as possible? |
The sample code: https://github.com/cjbi/quarkus-poi-bug-report Gitpod online demo: https://gitpod.io/new#https://github.com/cjbi/quarkus-poi-bug-report |
|
@cjbi can you check if adding the following dependency works for you? <dependency>
<groupId>io.quarkus</groupId>
<artifactId>quarkus-awt</artifactId>
</dependency> |
Thank you for your answer. However, Adding this dependency to my project, it still doesn't seem to be working. |
|
Sounds like you need to add that font to your native distribution, see https://quarkus.io/guides/writing-native-applications-tips#including-resources |
|
agreed with @gastaldi your native image can't find the Font you are trying to use. Font font = workbook.createFont();
font.setFontName("黑体");You need to include that font. Also note this issue with fonts: https://github.com/quarkiverse/quarkus-poi?tab=readme-ov-file#docker |
|
Thanks @gastaldi ，I removed the font, but it still didn't work. However，I found that when removed while (cellNo < cellLength) {
Cell cell = headRow.createCell(cellNo++);
// CellStyle style = workbook.createCellStyle();
// cell.setCellStyle(style);
cell.setCellValue("test name" + cellNo);
}Please look at the two lines of code with comments, when remove comments, it will cause an error.. |

Running my integration test now with that change |
|
Worked on Windows and Linux and ONLY fails on MacOS.
|
i don't used macos,I found github actions can also reproduce: |
|
@cjbi if you are using Red Hat ubi-minimal did you see this note: https://github.com/quarkiverse/quarkus-poi?tab=readme-ov-file#docker It won't work in ubi-minimal without that script. For example here is one of mine that uses POI Native in UbiMinimal: |
|
I'm sorry bro @melloware , i don't notice the readme, but it still doesn't work after adding. |
|
I wonder if it’s a bug in Mandrel. Can you change to GraalVM CE just to check? |
|
@zakkak any hints? |
|
@gastaldi I using graalvm-ce from https://www.graalvm.org/latest/docs/getting-started/container-images/, it also can’t working. |

Trying this without Investigating further one can see that when building that native image a bunch of library files are placed next to the application: Now if we move the binary to a different location, e.g. So what happens here is that the application depends on those library files, but the libraries are not transferred to the docker image. This looks like a known issue quarkusio/quarkus#32576 (comment) that slept through the cracks and never got fixed (cc @Karm). Patching the reproducer with: diff --git a/.dockerignore b/.dockerignore

works-around the issue. Thanks for bringing this to our attention! |

@zakkak Thanks for your help, i modified my code it's working fine. |

Thank you for the help @zakkak ! I'm going to close this now |

For the record, the upstream issue tracking this is quarkusio/quarkus#38412 |
in pom.xml I've:

when running on native image, an error will occur
when I'm running my project without native image it is running fine.
Output of java -version
