[LAU] OT java question

I am attempting to build the latest code from the Edisyn project, a cross-platform synth patch editor in java. https://github.com/eclab/edisyn I am not familiar with java, and need help interpreting what this error message implies is missing when building on linux: adding: META-INF/maven/uk.co.xfactory-librarians/(in = 0) (out= 0)(stored 0%) adding: META-INF/maven/uk.co.xfactory-librarians/coremidi4j/(in = 0) (out= 0)(stored 0%) adding: META-INF/maven/uk.co.xfactory-librarians/coremidi4j/pom.properties(in = 99) (out= 94)(deflated 5%) adding: META-INF/maven/uk.co.xfactory-librarians/coremidi4j/pom.xml(in = 9447) (out= 1866)(deflated 80%) adding: META-INF/services/(in = 0) (out= 0)(stored 0%) adding: META-INF/services/javax.sound.midi.spi.MidiDeviceProvider(in = 59) (out= 57)(deflated 3%) java.nio.file.NoSuchFileException: /tmp/edisyn.jar18028387212799341374.jar -> install/edisyn.jar at java.base/sun.nio.fs.UnixException.translateToIOException(UnixException.java:92) at java.base/sun.nio.fs.UnixException.rethrowAsIOException(UnixException.java:106) at java.base/sun.nio.fs.UnixCopyFile.move(UnixCopyFile.java:477) at java.base/sun.nio.fs.UnixFileSystemProvider.move(UnixFileSystemProvider.java:266) at java.base/java.nio.file.Files.move(Files.java:1432) at jdk.jartool/sun.tools.jar.Main.validateAndClose(Main.java:463) at jdk.jartool/sun.tools.jar.Main.run(Main.java:330) at jdk.jartool/sun.tools.jar.Main.main(Main.java:1683) make: *** [Makefile:24: jar] Error 1 My best guess is that there is an optional package involving Unix-style system specific functions for file handling exceptions, but I searched my distribution repositories (Fedora) for "java" then grepped "nio" "file" "exception" and "unix" but only found asynchronous network IO packages, nothing that looked like a package providing the file exception functions that seem to be missing. Either I am missing some name in the error messages and not searching for the right package, or something else is going on and I completely misinterpreted the error messages. Using the Java 17 JDK (latest LTS release, java-17-openjdk-17.0.4.0.8-1.fc36) and the git head from Edisyn downloaded today (1 Aug). Anyone else have experience with either building this package, or similar Java error messages and could point me in the right direction? -- Chris Caudle
