Question

我试图在我的Play 2.3.4（scala 2.10.4）应用中使用jacoco4sbt，但只有2.1.4似乎有用。当我使用.5或.6时，我收到以下错误：

[error] (main/jacoco:fullClasspath) java.lang.NoSuchMethodError:
org.objectweb.asm.MethodVisitor.visitMethodInsn(ILjava/lang/String;Ljava/lang/String;Ljava/lang/String;Z)V

我尝试将asm-all（版本4.1和5.0.3）添加到依赖项中，但这根本没有帮助。

那么可能是什么问题？我是否需要添加任何额外的依赖？

Answer 1

They have indeed changed the ASM version到5.0.1，即便如此，我也无法重现您的问题。

<强>项目/ build.properties

sbt.version=0.13.7-M3

<强>项目/ plugins.sbt

addSbtPlugin("com.typesafe.play" % "sbt-plugin" % "2.3.4")

<强>插件/ jacoco4sbt.sbt

addSbtPlugin("de.johoop" % "jacoco4sbt" % "2.1.6")

<强> build.sbt

name := """play-jacoco"""

version := "1.0-SNAPSHOT"

enablePlugins(PlayScala)

scalaVersion := "2.11.2"

libraryDependencies ++= Seq(
  jdbc,
  anorm,
  cache,
  ws
)

pipelineStages := Seq(rjs, digest, gzip)

jacoco.settings

当我跑jacoco:cover时，它工作正常。

我们在哪里有所不同？

Answer 2

在查看Jacek的答案并开始从我的项目中删除内容之后，我发现这是因为某些custom task运行PMD我不知道，这可能取决于不同的asm版本

要解决此问题，我只是更改了project/plugins.sbt中的依赖项以排除asm依赖项：

libraryDependencies ++= Seq(
  // (...)
  "net.sourceforge.pmd" % "pmd" % "5.1.3" exclude("org.ow2.asm", "asm")
)

Jacoco和PMD再次开始工作。

为什么Play 2.3.4和jacoco4sbt＆gt; 2.1.4 NoSuchMethodError失败？
