In spring boot application, I builded a jar with maven 3.9.5, and then run it: java -jar true-north.jar. PythonExecutioner.init got a error: java.lang.ExceptionInInitializerError: null at com.banji.truenorth.runner.ApplicationInitRunner.run(ApplicationInitRunner.java:16) at org.springframework.boot.SpringApplication.callRunner(SpringApplication.java:756) at org.springframework.boot.SpringApplication.lambda$callRunners$2(SpringApplication.java:746) at java.base/java.util.stream.ForEachOps$ForEachOp$OfRef.accept(ForEachOps.java:183) at java.base/java.util.stream.SortedOps$SizedRefSortingSink.end(SortedOps.java:357) at java.base/java.util.stream.AbstractPipeline.copyInto(AbstractPipeline.java:485) at java.base/java.util.stream.AbstractPipeline.wrapAndCopyInto(AbstractPipeline.java:474) at java.base/java.util.stream.ForEachOps$ForEachOp.evaluateSequential(ForEachOps.java:150) at java.base/java.util.stream.ForEachOps$ForEachOp$OfRef.evaluateSequential(ForEachOps.java:173) at java.base/java.util.stream.AbstractPipeline.evaluate(AbstractPipeline.java:234) at java.base/java.util.stream.ReferencePipeline.forEach(ReferencePipeline.java:497) at org.springframework.boot.SpringApplication.callRunners(SpringApplication.java:744) at org.springframework.boot.SpringApplication.run(SpringApplication.java:315) at org.springframework.boot.SpringApplication.run(SpringApplication.java:1300) at org.springframework.boot.SpringApplication.run(SpringApplication.java:1289) at com.banji.truenorth.TrueNorthApplication.main(TrueNorthApplication.java:16) at java.base/jdk.internal.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at java.base/jdk.internal.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at java.base/jdk.internal.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.base/java.lang.reflect.Method.invoke(Method.java:566) at org.springframework.boot.loader.MainMethodRunner.run(MainMethodRunner.java:49) at org.springframework.boot.loader.Launcher.launch(Launcher.java:108) at org.springframework.boot.loader.Launcher.launch(Launcher.java:58) at org.springframework.boot.loader.JarLauncher.main(JarLauncher.java:65) Caused by: java.lang.RuntimeException: java.io.FileNotFoundException: JAR entry org/bytedeco/cpython/windows-x86\_64/bin/python.exe not found in D:\java\_work\TrueNorth-Server\start\target\true-north.jar at org.nd4j.python4j.PythonExecutioner.initPythonPath(PythonExecutioner.java:363) at org.nd4j.python4j.PythonExecutioner.init(PythonExecutioner.java:79) at org.nd4j.python4j.PythonExecutioner.(PythonExecutioner.java:70) … 24 common frames omitted Caused by: java.io.FileNotFoundException: JAR entry org/bytedeco/cpython/windows-x86\_64/bin/python.exe not found in D:\java\_work\TrueNorth-Server\start\target\true-north.jar at org.springframework.boot.loader.jar.JarURLConnection.throwFileNotFound(JarURLConnection.java:175) at org.springframework.boot.loader.jar.JarURLConnection.connect(JarURLConnection.java:98) at org.springframework.boot.loader.jar.JarURLConnection.getJarFile(JarURLConnection.java:106) at org.bytedeco.javacpp.Loader.extractResource(Loader.java:777) at org.bytedeco.javacpp.Loader.extractResource(Loader.java:756) at org.bytedeco.javacpp.Loader.extractResource(Loader.java:803) at org.bytedeco.javacpp.Loader.cacheResource(Loader.java:684) at org.bytedeco.javacpp.Loader.cacheResource(Loader.java:477) at org.bytedeco.javacpp.Loader.cacheResource(Loader.java:444) at org.bytedeco.javacpp.Loader.cacheResource(Loader.java:432) at org.bytedeco.cpython.presets.python.cachePackage(python.java:222) at org.bytedeco.cpython.presets.python.cachePackages(python.java:264) at org.nd4j.python4j.PythonExecutioner.cachePackages(PythonExecutioner.java:372) at org.nd4j.python4j.PythonExecutioner.initPythonPath(PythonExecutioner.java:323) … 26 common frames omitted ---

@aizhimin same ask as on the issue. Please post more information to make sure it’s not a native loading issue. This: Caused by: java.io.FileNotFoundException: JAR entry org/bytedeco/cpython/windows-x86\_64/bin/python.exe not found in D:\java\_work\TrueNorth-Server\start\target\true-north.jar at either indicates the python file has a native (think dll hell) type conflict or you’re missing something in your dependencies. While you’re at it, could you post your pom.xml please? I don’t want any company secrets or anything just the relevant parts mainly. python4j and spring boot and any other open source 3rd party libraries you might be using. ---

@aizhimin that’s already fixed in the latest then.I would try forcing the javacpp 1.5.9 dependency via dependemcnyManagement.
