From a18ed19cbc3c3137fd9cd8a294278b1426035baa Mon Sep 17 00:00:00 2001 From: Eugene Yokota Date: Sun, 15 Dec 2024 02:47:35 -0500 Subject: [PATCH] fix: Use JDK path, not JRE path **Problem** There are a few places where javaHome or java path is set, using java.home system property. The problem is that it points to JRE, not JDK, so it would break on Java compilation etc. **Solution** If the path ends with jre, go up one directory. --- .../main/scala/sbt/internal/util/Util.scala | 5 +++++ main/src/main/scala/sbt/Defaults.scala | 6 ++--- .../internal/bsp/BuildServerConnection.scala | 3 ++- .../test/scala/testpkg/BuildServerTest.scala | 22 +++++++++++++------ 4 files changed, 24 insertions(+), 12 deletions(-) diff --git a/internal/util-collection/src/main/scala/sbt/internal/util/Util.scala b/internal/util-collection/src/main/scala/sbt/internal/util/Util.scala index c182bad16..4e4d3e8b7 100644 --- a/internal/util-collection/src/main/scala/sbt/internal/util/Util.scala +++ b/internal/util-collection/src/main/scala/sbt/internal/util/Util.scala @@ -8,6 +8,7 @@ package sbt.internal.util +import java.nio.file.{ Path, Paths } import java.util.Locale import scala.reflect.macros.blackbox @@ -121,4 +122,8 @@ object Util { case g: ThreadId @unchecked => g.threadId } } + + lazy val javaHome: Path = + if (sys.props("java.home").endsWith("jre")) Paths.get(sys.props("java.home")).getParent() + else Paths.get(sys.props("java.home")) } diff --git a/main/src/main/scala/sbt/Defaults.scala b/main/src/main/scala/sbt/Defaults.scala index f3a36453c..0b54ba2e5 100644 --- a/main/src/main/scala/sbt/Defaults.scala +++ b/main/src/main/scala/sbt/Defaults.scala @@ -9,8 +9,7 @@ package sbt import java.io.{ File, PrintWriter } -import java.net.{ URI, URL } -import java.nio.file.{ Paths, Path => NioPath } +import java.nio.file.{ Path => NioPath } import java.util.Optional import java.util.concurrent.TimeUnit import lmcoursier.CoursierDependencyResolution @@ -408,13 +407,12 @@ object Defaults extends BuildCommon { val boot = app.provider.scalaProvider.launcher.bootDirectory val ih = app.provider.scalaProvider.launcher.ivyHome val coursierCache = csrCacheDirectory.value - val javaHome = Paths.get(sys.props("java.home")) Map( "BASE" -> base.toPath, "SBT_BOOT" -> boot.toPath, "CSR_CACHE" -> coursierCache.toPath, "IVY_HOME" -> ih.toPath, - "JAVA_HOME" -> javaHome, + "JAVA_HOME" -> Util.javaHome, ) }, fileConverter := MappedFileConverter(rootPaths.value, allowMachinePath.value), diff --git a/protocol/src/main/scala/sbt/internal/bsp/BuildServerConnection.scala b/protocol/src/main/scala/sbt/internal/bsp/BuildServerConnection.scala index e03b67eae..ba9042dde 100644 --- a/protocol/src/main/scala/sbt/internal/bsp/BuildServerConnection.scala +++ b/protocol/src/main/scala/sbt/internal/bsp/BuildServerConnection.scala @@ -9,6 +9,7 @@ package sbt.internal.bsp import sbt.internal.bsp.codec.JsonProtocol.BspConnectionDetailsFormat +import sbt.internal.util.Util import sbt.io.IO import sjsonnew.support.scalajson.unsafe.{ CompactPrinter, Converter } @@ -25,7 +26,7 @@ object BuildServerConnection { private[sbt] def writeConnectionFile(sbtVersion: String, baseDir: File): Unit = { val bspConnectionFile = new File(baseDir, ".bsp/sbt.json") - val javaHome = System.getProperty("java.home") + val javaHome = Util.javaHome val classPath = System.getProperty("java.class.path") val sbtScript = Option(System.getProperty("sbt.script")) diff --git a/server-test/src/test/scala/testpkg/BuildServerTest.scala b/server-test/src/test/scala/testpkg/BuildServerTest.scala index c24694587..0c0306fe9 100644 --- a/server-test/src/test/scala/testpkg/BuildServerTest.scala +++ b/server-test/src/test/scala/testpkg/BuildServerTest.scala @@ -228,7 +228,6 @@ object BuildServerTest extends AbstractServerTest { val buildTarget = buildTargetUri("javaProj", "Compile") compile(buildTarget) - assertMessage( "build/publishDiagnostics", "Hello.java", @@ -251,16 +250,17 @@ object BuildServerTest extends AbstractServerTest { val testFile = new File(svr.baseDirectory, s"java-proj/src/main/java/example/Hello.java") val otherBuildFile = new File(svr.baseDirectory, "force-java-out-of-process-compiler.sbt") - // Setting `javaHome` will force SBT to shell out to an external Java compiler instead + // Setting `javaHome` will force sbt to shell out to an external Java compiler instead // of using the local compilation service offered by the JVM running this SBT instance.
